In fpGUI the rsThousandSeparator contains the locale specific character in UTF-8 encoding. Also ThousandSeparator := Utf8toAnsi(rsThousandSeparator) is not compilable because Utf8ToAnsi() returns a string, not a Char. And simply casting the result to a Char might not be a good idea in all cases. This issue obviously affects more that just the FormatFloat() function. It affects any functions using FPC locale variables defined as Char and the UTF8toAnsi() result is more that one byte.
