Knock yourself out... https://github.com/graemeg/fpGUI/blob/master/src/corelib/fpg_stringutils.pas Take a look at UTF8Copy() or UTF8Insert() etc. > in FPC, until now.

Consider a Copy() type function where you want to copy a Unicode codepoint (think single character as you see on the screen - ignoring combining diacritics for now) out from a string. UTF8Copy() as defined above will do that correctly, irrespective if the codepoint is in the BMP or Supplementary Plane or if the character is represented by 1,2,3 or 4 bytes in length. With UTF-16 you need to check if the UTF-16 string is Little Indian or Big Indian (UTF-16BE or UTF-16LE), whether the codepoint has a surrogate pair or not. All in all, a lot more complex than UTF-8.
