If you compile with -vh, then the compiler will tell you which function definitions it found:

tt.pp(4,11) Error: Can't determine which overloaded function to call
wstrings.inc(1623,10) Hint: Found declaration: UTF8Encode(const WideString):AnsiString;
ustrings.inc(2281,10) Hint: Found declaration: UTF8Encode(const UnicodeString):AnsiString;

The reason it works on Unix platforms, is that widestring=unicodestring there (so there is nothing to choose between if you pass a wide/unicodechar). You can solve it by typecasting the character explicitly to either widestring or unicodestring.
