If these things matter to you, it's better to convert from UTF-8 to Unicode, first. I tend to think of Unicode as an arbitrarily large code page. Each character maps to a number, but that number could be 1, 1000 or 500_000 (Unicode seems to be growing without might end in sight). Internally, you might store those code points as Integers or QUad Words or whatever you like. Only once you're ready to transfer the text to another process (print on screen, save to a file, stream across a network), do you convert the Unicode back into UTF-8. Basically, you consider UTF-8 to be a transfer-only format (like Base64). If you want to do anything non-trivial with it, decode it into Unicode. > >With ASCII and the many encodings based on it, most things can >be done without having knowledge of the encoding.
