Question mark is often used for characters that have no code point in the charset. So, what is the code point of the character that turns into a question mark? Does that same code point output okay some of the time? Of course, this explanation is a bit dubious if input is UTF-8, internal encoding is UTF-8 and output is UTF-8. > More details for an instant: - Only characters read from a utf-8 > encoded file with a function file_get_contents() seem to be displayed > correctly at all times; - Characters that are read by the php.exe > (please excuse me here) do fail once in a while Ah, could you be reading a partial multi-byte character and processing it? E.g. taking an extreme example if you read 8 bytes, process them, then repeat with the next 8 bytes, and they are an equal mix of characters 1, 2 and 3 bytes long then there is a high probability you will processing garbage.
