It might be technically possible to recreate internal implementation, or get the byte data. That does not mean it will make any sense or be understood in a meaningful manner. I think Ian summarized it very well: >You can't generally just "deal with the ascii portions" without >knowing something about the encoding. Say you encounter a byte >greater than 127. Is it a single non-ASCII character, or is it the >leading byte of a multi-byte character? If the next character is less >than 127, is it an ASCII character, or a continuation of the previous >character? For UTF-8 you could safely assume ASCII, but without >knowing the encoding, there is no way to be sure. If you just assume >it's ASCII and manipulate it as such, you could be messing up >non-ASCII characters. Technically, ASCII goes up to 256 but they are not A-z letters.
