Multibyte ansi chars are still not unique and require the code page for
proper interpretation, this is why Unicode has been invented. By using
properly functions like ChartoByteIndex or NextCharIndex, it makes very
likely no difference for string processing code if the strings are multi
byte ansi or utf-8 unicode.
