Hi,

I don’t know what is the character encoding of string literals on your 
system (perhaps just the encoding your editor is saving as), but yes, 
cairo_show_text does support Unicode and expects a NUL-terminated UTF-8 
string.

But this is a the "toy" text API, you might get better results with Pango.
