// You would think *printf are simple, right? Iterate on each character,
// if it's a format specifier handle it properly, etc.
//
// Nooooo. Not according to the C standard.
//
// According to the C99 standard (7.19.6.1 "The fprintf function")
// The format shall be a multibyte character sequence
//
// Because some character encodings might have '%' signs in the middle of
// a multibyte sequence (SJIS for example only specifies that the first
// byte of a 2 byte sequence is "high", the second byte can be anything),
// printf functions have to decode the multibyte sequences and try their
// best to not screw up.
//
// Unfortunately, on Windows, the locale for most languages is not UTF-8
// as we would need. Notably, for zh_TW, Windows chooses EUC-CN as the
// locale, and completely fails when trying to decode UTF-8 as EUC-CN.
//
// On the other hand, the fix is simple: because we use UTF-8, no such
// multibyte handling is required as we can simply assume that no '%' char
// will be present in the middle of a multibyte sequence.
//
// This is why we lookup an ANSI (cp1252) locale here and use _vsnprintf_l.
