Re: [PATCH 0/2] MR8198: ucrtbase: Fix case mapping and ctype1 info for UTF8 locale.

[Paul Gofman (＠gofman)]

That, in particular, fixes a crash in Crysis 2 Remastered which is happening after commit a0e2cbd46a7e629005ff306f032b02c263362775.

At least for UTF8 locale WideCharToMultiByte() always fails in create_locinfo(). The code doesn't assume any failures there (leaving potentially initialized data), I guess such a case warrants a FIXME (patch 1). Currently tolower() / toupper() for utf8 chars 128-255 locale will return some bogus characters instead of unchanged input character.

Then, GetCPInfo(CP_UTF8, ...) doesn't report any LeadBytes (also on Windows) which I guess pretty much warrants special handling for utf8 in ucrtbase.
