Hi, thanks for contributing!

Could you please provide a little more context about the issue? I just came across it, but I’m not fully clear on what was missing and how this PR fixes the issue.

Hi @perminder-17 , thank you for the review and the doubt regarding the PR :
This PR fixes a bug where the optional CRLF flag was being dropped when saving text files through save(). The issue was that save() passed only three arguments to saveStrings(), so true for Windows-style \r\n line endings never reached the actual writer. The fix forwards the missing fourth argument, so text files can correctly preserve CRLF when requested.

The main consequence is that text files saved via save() would always use \n line endings, even when the caller explicitly asked for CRLF (true). That can cause Windows-style line-ending expectations to fail, especially when files are opened or processed by tools that rely on \r\n for compatibility.
