On Windows, Perl automatically converts CRLF to LF on read, and LF to CRLF on write (by default).

But you might be using a perl built as part of unix emulation environment like Cygwin and I think MSYS/MSYS2. Such a Perl wouldn't perform such translations, even though it could be launched from a Windows program (e.g. the Windows shell).

Possible solutions:

• You could install a native build of Perl (Strawberry Perl or ActivePerl).
• You could convert the file's line endings (e.g. using Perl or dos2unix).
• You could monkeypatch the module. (See haukex's answer.)
• You could patch the module.
