- WideStringUpperCase moved to UUnicodeUtils.pas

- WideCharUpperCase removed as single characters (code-point) can be represented by two WideChars (surrogates). Convert to UCS4 instead (one code-point <-> one UCS4Char).
- UCS4 functions added to UUUnicodeUtils
- string replaced with UTF8String (although it's just a typedef) to mark UTF8 strings.
