Witryna4 maj 2016 · The problem, we believe, has to do with the fact that imread can only take in a std::string (or char* ), and casting a path with non Latin-1 symbols to a std::string results in characters that use multiple bytes in UTF-8 (the encoding used for QString, which is how we store the paths) being converted to multiple chars.
