SDL_ttf and Wingdings font under Linux

Hello,

I’m trying to use the Wingdings TTF font (coming from Windows) with SDL_ttf
2.0.6 but all I get are [] (empty square) characters. I’ve tried the
UNICODE_* and UTF8_* functions, with either Glyph or Text but it’s always
the same result.

So, has anyone suceedeed ? The symbols in this font are very useful and
(should) scale nicely.

Thanks.

Damiano
