Detailed Description

+
template<typename UtfType, Endian E>
+class utf::string::String< UtfType, E >

Owning container for UTF-encoded strings with Small String Optimization.

+
Template Parameters
+ + + +
UtfTypeThe UTF encoding type (Utf8, Utf16, or Utf32)
EThe endianness (Endian::None for UTF-8, BE or LE for UTF-16/32)
+
+
+

Total size is 32 bytes. Inline capacities:

    +
  • UTF-8: ~16 units (exact: (32 - 17) / 1)
  • +
  • UTF-16: ~7 units (exact: (32 - 17) / 2)
  • +
  • UTF-32: ~3 units (exact: (32 - 17) / 4) Strings exceeding inline capacity are heap-allocated.
    Note
    Iterator Invalidation: append(), reserve(), operator+=, operator+ may invalidate iterators
    +
    +Exception Safety: Strong guarantee for copy operations, basic guarantee for modifications

3// utf_string.hpp - Modern C++23 UTF String Library
+
4//
+
5// A type-safe, constexpr-enabled library for handling UTF-8, UTF-16, and UTF-32
+
6// strings with explicit endianness control. Built on top of utf_codepoint.hpp.
+
7//
+
8// Features:
+
9// - UTF-8/16/32 string views and containers
+
10// - Small String Optimization (SSO) - strings <= 32 bytes stored on stack
+
11// - Iterator support for code point traversal
+
12// - String conversion between encodings (explicit constructors and assignment)
+
13// - String concatenation operators
+
14// - Validation and sanitization
+
15// - constexpr and noexcept throughout for zero runtime overhead
+
16// - Range-based operations
+
17//
+
18// Requirements:
+
19// - C++23 or later
+
20// - utf_codepoint.hpp (included automatically)
+
21// - Standard library support for: <string>, <string_view>, <ranges>
+
22//
+
23// Example Usage:
+
24// // Create UTF-8 string view
+
25// utf::string::Utf8StringView sv{u8"Hello δΈ–η•Œ πŸ’©"};
+
26//
+
27// // Iterate over code points
+
28// for (auto cp : sv) {
+
29// // cp is utf::Utf8CodePoint
+
30// if (cp.is_valid()) {
+
31// auto scalar = cp.to_scalar();
+
32// // ...
+
33// }
+
34// }
+
35//
+
36// // Convert between encodings (now with direct assignment!)
+
37// utf::string::Utf32BEString u32{0x1F4A9};
+
38// utf::string::Utf8String u8{u32}; // Converting constructor
+
39// u8 = u32; // Converting assignment
+
40//
+
41// // String concatenation
+
42// auto combined = u8 + u8;
+
43// u8 += utf::Utf8CodePoint{0x21}; // Append '!'

Detailed Description

+
template<typename StorageType>
+class utf::string::SmallStringBuffer< StorageType >

Small buffer optimization for UTF strings.

+

Strings up to 32 bytes total (including metadata) are stored inline on the stack. Actual data capacity is 32 - 2*sizeof(size_t) bytes.

Note
StorageType must be trivially copyable (enforced by static_assert)

struct CodePoint<Utf8
+
+

UTF-8 code point representation.

+

UTF-32 code point representation.

+

UTF-16 code point representation.

+

Stores a single Unicode code point encoded as UTF-8 (1-4 bytes). Total size: exactly 4 bytes (optimal alignment).

+

UTF-8 is byte-oriented so endianness does not apply. Length is computed on-demand from the leading byte pattern.

+
Note
Construction may create invalid code points. Always check is_valid() after construction, or use from_scalar() factory function for safe construction. Default construction creates U+0000 (null character), which is a valid code point.
+
Template Parameters
+ + +
EEndianness (must be BE or LE, not None)
+
+
+

Stores a single Unicode code point encoded as UTF-16 (1-2 units). Total size: exactly 4 bytes (optimal alignment). Handles both BMP characters (single unit) and supplementary characters (surrogate pairs). Length is computed on-demand from surrogate detection.

+
Note
Construction may create invalid code points. Always check is_valid() after construction, or use from_scalar() factory function for safe construction. Default construction creates U+0000 (null character), which is a valid code point.
+
Template Parameters
+ + +
EEndianness (must be BE or LE, not None)
+
+
+

Stores a single Unicode code point as a single UTF-32 unit. Total size: exactly 4 bytes (optimal alignment). This is the simplest encoding where one unit always equals one code point.

+
Note
Construction may create invalid code points. Always check is_valid() after construction, or use from_scalar() factory function for safe construction. Default construction creates U+0000 (null character), which is a valid code point.

3// utf_codepoint.hpp - Modern C++23 UTF Code Point Library
+
4//
+
5// A type-safe, constexpr-enabled library for handling UTF-8, UTF-16, and UTF-32
+
6// code points with explicit endianness control.
+
7//
+
8// Features:
+
9// - UTF-8/16/32 encoding and decoding
+
10// - Explicit endianness control (Big Endian / Little Endian)
+
11// - Compile-time validation via concepts
+
12// - constexpr and noexcept throughout for zero runtime overhead
+
13// - Safe construction via factory functions returning std::optional
+
14// - Full validation including overlong encoding detection
+
15// - Optimal memory layout: all CodePoint types are exactly 4 bytes
+
16//
+
17// Requirements:
+
18// - C++23 or later
+
19// - Standard library support for: <bit>, <span>, <concepts>, <optional>
+
20//
+
21// Example Usage:
+
22// // Create UTF-8 code point from Unicode scalar
+
23// auto cp = utf::Utf8CodePoint::from_scalar(0x1F4A9); // πŸ’©
+
24// if (cp) {
+
25// // Convert to UTF-16 Little Endian
+
26// auto u16 = utf::convert<utf::Utf16LECodePoint>(*cp);
+
27// if (u16) {
+
28// // Use the code point
+
29// auto scalar = u16->to_scalar();
+
30// }
+
31// }
+
32//
+
33// // Fast path when input is known to be valid
+
34// utf::Utf8CodePoint valid_cp{0x41}; // 'A'
+
35// auto u32 = utf::convert_unchecked<utf::Utf32BECodePoint>(valid_cp);

Detailed Description

+

Central UTF Strings library header - main API entry point.

+

This is the primary header for the UTF Strings library. It provides a unified namespace and includes all necessary components for working with UTF-8, UTF-16, and UTF-32 strings with explicit endianness control.

+

Features:

    +
  • UTF-8/16/32 string views and containers
  • +
  • Small String Optimization (SSO) - strings <= 32 bytes stored on stack
  • +
  • Iterator support for code point traversal
  • +
  • String conversion between encodings
  • +
  • String concatenation operators
  • +
  • Validation and sanitization
  • +
  • constexpr and noexcept throughout for zero runtime overhead
  • +
  • Range-based operations
  • +
  • Factory methods for creating strings from byte arrays
  • +
+

Requirements:

    +
  • C++23 or later
  • +
  • Standard library support for: <string>, <string_view>, <ranges>
  • +
+

Example Usage:

#include <utf.hpp>
+
+
// Create UTF-8 string view
+
utf::string::Utf8StringView sv{u8"Hello δΈ–η•Œ πŸ’©"};
+
+
// Iterate over code points
+
for (auto cp : sv) {
+
if (cp.is_valid()) {
+
auto scalar = cp.to_scalar();
+
// ...
+
}
+
}
+
+
// Convert between encodings
+ +
utf::string::Utf8String u8{u32}; // Converting constructor
+
u8 = u32; // Converting assignment
+
+
// Factory methods from byte arrays
+
std::array<uint8_t, 4> utf8_bytes = {0x48, 0x65, 0x6C, 0x6C}; // "Hell"
+
auto utf8_str = utf::string::Utf8String::from_bytes(utf8_bytes.data(), utf8_bytes.size());
+
if (utf8_str.has_value()) {
+
// Use the string
+
}
+
+
// String concatenation
+
auto combined = u8 + u8;
+
u8 += utf::Utf8CodePoint{0x21}; // Append '!'
+

Graph Legend
+
+
+

This page explains how to interpret the graphs that are generated by doxygen.

+

Consider the following example:

/*! Invisible class because of truncation */
+
class Invisible { };
+
+
/*! Truncated class, inheritance relation is hidden */
+
class Truncated : public Invisible { };
+
+
/* Class not documented with doxygen comments */
+
class Undocumented { };
+
+
/*! Class that is inherited using public inheritance */
+
class PublicBase : public Truncated { };
+
+
/*! A template class */
+
template<class T> class Templ { };
+
+
/*! Class that is inherited using protected inheritance */
+
class ProtectedBase { };
+
+
/*! Class that is inherited using private inheritance */
+
class PrivateBase { };
+
+
/*! Class that is used by the Inherited class */
+
class Used { };
+
+
/*! Super class that inherits a number of other classes */
+
class Inherited : public PublicBase,
+
protected ProtectedBase,
+
private PrivateBase,
+
public Undocumented,
+
public Templ<int>
+
{
+
private:
+
Used *m_usedClass;
+
};
+

This will result in the following graph:

+

The boxes in the above graph have the following meaning:

+
    +
  • +A filled gray box represents the struct or class for which the graph is generated.
  • +
  • +A box with a black border denotes a documented struct or class.
  • +
  • +A box with a gray border denotes an undocumented struct or class.
  • +
  • +A box with a red border denotes a documented struct or class forwhich not all inheritance/containment relations are shown. A graph is truncated if it does not fit within the specified boundaries.
  • +
+

The arrows have the following meaning:

+
    +
  • +A blue arrow is used to visualize a public inheritance relation between two classes.
  • +
  • +A dark green arrow is used for protected inheritance.
  • +
  • +A dark red arrow is used for private inheritance.
  • +
  • +A purple dashed arrow is used if a class is contained or used by another class. The arrow is labelled with the variable(s) through which the pointed class or struct is accessible.
  • +
  • +A yellow dashed arrow denotes a relation between a template instance and the template class it was instantiated from. The arrow is labelled with the template parameters of the instance.

UTF Strings - Cross-Platform C++23 Library
+
+
+

CI/CD Pipeline SAST Security Scanning CodeQL Security Analysis Extended Fuzz Testing Release Validation

+

C++23 CMake Conan License

+

Linux Windows macOS

+

Performance Security Quality

+

Modern C++23 UTF utilities (UTF-8/16/32) with explicit endianness policy and comprehensive testing.

+

Cross-Platform Support:

    +
  • Linux: GCC 13+ or Clang 18+
    +
  • +
  • Windows: MSVC 2022 or Clang-CL 16+
  • +
  • macOS: Clang 16+ (Apple Clang or LLVM)
  • +
+

Key Features:

    +
  • πŸš€ Single Bootstrap Configuration - One command for complete setup
  • +
  • πŸ”’ Security Hardened - Stack protection, ASLR, DEP, Control Flow Integrity
  • +
  • ⚑ Performance Optimized - LTO, native CPU optimization, vectorization
  • +
  • πŸ§ͺ Comprehensive Testing - Unit tests, fuzz testing, sanitizers, benchmarks
  • +
  • 🎯 Code Quality - clang-format integration, extensive warnings, static analysis
  • +
+

+

+Quick Start

+

+Automated Setup (Recommended)

+

Linux/macOS:

./bootstrap_cmake.sh # Auto-detect compiler and full setup
+
./bootstrap_cmake.sh --compiler gcc # Force GCC
+
./bootstrap_cmake.sh --compiler clang # Force Clang
+

Windows (cmd/PowerShell):

bootstrap_cmake.bat # Auto-detect and full setup
+

That's it! The bootstrap script will:

    +
  • βœ… Detect your platform and available compilers
  • +
  • βœ… Install missing tools (CMake, Conan, clang-format)
  • +
  • βœ… Configure optimized builds (Debug + Release)
  • +
  • βœ… Run comprehensive tests and benchmarks
  • +
  • βœ… Set up development environment
  • +
+

+Manual Setup (Advanced)

+

If you prefer manual control:

+
# Install dependencies
+
conan install . -s build_type=Debug --output-folder=build --build=missing
+
conan install . -s build_type=Release --output-folder=build --build=missing
+
+
# Configure (using presets)
+
cmake --preset conan-debug # Debug build
+
cmake --preset conan-release # Release build
+
+
# Build
+
cmake --build --preset conan-debug --parallel
+
cmake --build --preset conan-release --parallel
+
+
# Test
+
build/Debug/utf_strings-tests # Linux/macOS
+
build\Debug\utf_strings-tests.exe # Windows
+
+
# Benchmark
+
build/build/utf_strings-bench --benchmark_min_time=0.1s
+

+Advanced Compiler Configuration

+

The build system supports fine-grained compiler control through external flags:

+
# Standard optimized build
+
cmake --preset conan-release \
+
-DCOMPILER_TYPE=GCC \
+
-DUSE_LTO=ON \
+
-DUSE_NATIVE_ARCH=ON \
+
-DENABLE_SHARED_LIBRARY=ON
+
+
# Maximum performance build (Clang with libc++)
+
cmake --preset conan-release \
+
-DCOMPILER_TYPE=CLANG \
+
-DUSE_LTO=ON \
+
-DUSE_NATIVE_ARCH=ON \
+
-DUSE_LIBC_PLUS_PLUS=ON \
+
-DENABLE_SHARED_LIBRARY=ON
+
+
# Debug-friendly build (no aggressive optimizations)
+
cmake --preset conan-debug \
+
-DCOMPILER_TYPE=CLANG \
+
-DUSE_LTO=OFF \
+
-DUSE_NATIVE_ARCH=OFF \
+
-DENABLE_SHARED_LIBRARY=OFF
+

Available Configuration Flags:

    +
  • COMPILER_TYPE: GCC|CLANG|MSVC - Explicit compiler identification
  • +
  • USE_LTO: ON|OFF - Link Time Optimization
  • +
  • USE_NATIVE_ARCH: ON|OFF - Native CPU optimization (-march=native)
  • +
  • USE_MSVC_LTO: ON|OFF - MSVC-specific LTO flags (/LTCG, /GL)
  • +
  • USE_LIBC_PLUS_PLUS: ON|OFF - Use libc++ instead of libstdc++ (Clang only)
  • +
  • ENABLE_SHARED_LIBRARY: ON|OFF - Build shared libraries
  • +
+
