NO, it doesn't! You can't use FPC's Copy(), Pos() etc reliably with
UTF-8 text, because thouse RTL functions work purely on ANSI text
(1-byte characters - speaking of String type text here) and don't know
about multi-byte characters, combining diacritics etc. Hence LCL and
fpGUI have special functions similar to RTL, that knows how to work with
UTF-8 encoded text. eg: UTF8Pos(), UTF8Length and UTF8Copy() etc functions.
