Yes, I want to allow multibyte input. Users > shouldn't have to jump through hoops to use these functions. FWIW, I disagree. You should check that either the string is unibyte (AKA byte_size<0) or that it's ASCII-only (byte_size==size). Forcing your users to (de|en)code explicitly before calling your functions isn't making them jump through hoops: it's helping them have the correct mental model of what "multibyte text" means. Stefan
