function UTF8ToUnicode(Dest: PUnicodeChar; MaxDestChars: SizeUInt;

a) it has "If (PreChar<>13) and FALSE then" and later some big block.
with a comment which tells that "and FALSE" is on purpose and block is
ignored. ?????
b) after I removed "that block" I got such trimmed src
Hello,
As the author of that piece of code, UTF8 recommends expanding LF line
endings to CR+LF but this will generate some troubles and to try to 100%
conform the spec. the conversion has been added, but disabled so code
maintainers can easily remove them if needed. If you remove the piece of
code about #13 you can safely remove the check about #10 which is now
nonsense so you end with:
-------------------
while (OutputUnicode<MaxDestChars) and (InputUTF8<SourceBytes) do
begin
IBYTE:=byte(Source[InputUTF8]);
if (IBYTE and $80) = 0 then
begin
//One character US-ASCII, convert it to unicode
Dest[OutputUnicode]:=WideChar(IBYTE);
inc(OutputUnicode);
PreChar:=IBYTE;
inc(InputUTF8);
------------------
Have a nice day.
