today I talked to behdad in #cairo He gave me these instructions after reading my code:
(02:03:59) *behdad:* JucaBlues: the new text_to_glyph areguments are mandoatry (02:04:08) behdad: and you shouldn't ignore utf8_len (02:04:09) behdad: really (02:04:19) behdad: forget about the old api (02:04:26) behdad: it was never in a released version of cairo (02:05:43) *behdad:* JucaBlues: also you shouldn't use malloc for glyphs anymore. (02:06:03) *behdad:* JucaBlues: read the new cairo_user_scaled_font_text_to_glyphs_func_t docs and implement it (02:06:58) behdad: your code also is not utf8-clean (02:07:27) *Juca:* :-P (02:07:38) *Juca:* so I have lots of stuff to work on (02:08:30) *Juca:* what do you mean by utf8-clean? (02:08:57) behdad: use g_utf8_* functions to deal with text (02:09:03) behdad: instead of assuming one char = one byte (02:09:08) *Juca:* ah (02:09:10) *Juca:* great! (02:09:41) *Juca:* I didnt now that but I was sure there was a correct way of coding it (02:09:56) *Juca:* and I suspected mine was wrong
