Bug ID: 49694 Summary: mc.exe: UTF-16 decoding does not use UTF-16LE by default, breaking files without a BOM Product: Wine Version: 5.14 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: ppdplayer@gmail.com Distribution: ---
Created attachment 67936 --> https://bugs.winehq.org/attachment.cgi?id=67936 Two .mc Files, BOM.mc with a proper UTF-16LE BOM, and NOBOM.mc with no UTF-16LE BOM.
Tested on both wine-staging and wine-vanilla on WINEARCH=win64 using VS-16.5 (and the latest installed though the script VS-16.7) though I suspect this isn't a program exclusive bug.
When building reactos using msvc on linux, I ran into this bug when building the .mc files. They are not generated with a UTF-16LE BOM, which Wine does not properly handle and will fail compilation.
Steps to Reproduce: 1. Download and install VS-16 using https://github.com/mstorsjo/msvc-wine Sidenote: You may install VS-16 however you like, we just need mc.exe for this. The script may give socket timeout errors, that's normal. Just retry. You will also need msiextract and libgcab to run the script. 2. Using "kits/10/bin/10.0.18362.0/x86/mc.exe -u" or "kits/10/bin/10.0.18362.0/x64/mc.exe -u" compile the attached BOM.mc and observe no errors. 3. Using the same programs, observe compiling NOBOM.mc and seeing the error: z:/home/<censored>/Downloads/tmp/NOBOM.mc(1) : error : expected keyword - M
