+# Regression guard for issue #1603.

+# The module .psm1 files are assembled by concatenating the per-cmdlet .ps1 source
+# files under module/. When a source file contains non-ASCII characters (for example
+# the arrow "->", an em dash, or a check mark) and is saved without a UTF-8 BOM,
+# Windows PowerShell 5.1 decodes the bytes using the system ANSI code page instead of
+# UTF-8. The mis-decoded multi-byte characters turn into stray quote characters that
+# unbalance the surrounding strings, so Import-Module fails with parser errors such as
+# "Missing closing ')' in expression" and "The string is missing the terminator".
+#
+# PowerShell 7 (Core) reads BOM-less files as UTF-8, which is why the CI test runs and
+# every day-to-day PowerShell 7 user import the module without error while the module
+# is broken on Windows PowerShell 5.1. Keeping the shipped source ASCII-only makes the
+# generated .psm1 parse identically under every encoding.
