If you convert from up to BUFFER_SIZE octets of UTF-8 input, you should never get back more than BUFFER_SIZE code units of UTF-16 output. Worst case would be ASCII, which is one UTF-16 code unit per UTF-8 octet, everything else is less (non-BMP is four UTF-8 octets mapping to two UTF-16 code units). > You're right for MultiByteToWideChar. However, the next patch series will introduce another conversion function that converts invalid UTF-8 to hex code, i.e. two wide chars per invalid UTF-8 char, +1 for L'\0' (see [1] mingw.h:365ff for space requirement rationale). And yet another patch will replace this patch's MultiByteToWideChar for consistentcy [2].
