[Devel] Problem with special characters

[José Carlos García Rufino]

How can I use freetype2 for rendering specials characters as áéíóúÁÉÍÓÚñÑ?

 

I use arial.ttf font and windows 2000pro

I'm able to rendering the others characters, but those specials characters don't work right.The rendering result of those characters is a white mark.

I use 256 gray-scale rendering

 

Please help me.

Thanks.
