Installer log

After working around bug https://bugs.winehq.org/show_bug.cgi?id=47626 the
installer fails while installing VisualStudio.TextMateGrammars due to a bug in
unicode file name handling.

The file is "File(Glob …).tmSnippet"

I can create the file manually or even from Far running in wine. But the
installer fails.

Tested on wine-staging 4.17-git
