How to convert ascii string to utf ?

[hm <z_b_r poczta fm>]

Hi !

  I`ve got a problem, when i`m tryin` to use gtk_text_buf_insert (). I don`t know how to convert an ascii string, which is loaded from file, let`s say , to a array : char c[255]; or gchar c[255];
How to convert that ascii to utf ? thanks for any help. I`m noob in gtk
