d.text.freetype already handles the lack of iconv(); look at
convert_text() in d.text.freetype/main.c.

You just need a hard-coded conversion to UCS-2 for the case where
iconv() is unavailable. ISO-8859-1 -> UCS-2 (used by d.text.freetype)
is trivial; a built-in UTF-8 -> UCS-2 converter wouldn't be a lot of
work.

Alternatively, you could use mbstowcs() to convert according to the
current locale.
