Native UTF-8 support is something that Windows developers have wanted for years. I thought it was impossible because of some API limitation where it assumed multibyte characters could only be three bytes long, but maybe this assumption has been removed. EDIT: So I just tested this. It does seem to affect the ANSI Windows APIs: https://0x0.st/siCS.png https://0x0.st/siCS.png Unfortunately, this doesn't mean the average Win32 program will be able to start using UTF-8 internally, since the ANSI codepage is a system-wide setting, so you won't be able to opt-in to UTF-8 per-process (at least, I don't think this is possible.)
