It is because UTF-8 is a multibyte encoding, and any one character may require between 1 and 5 bytes to represent it. If you were allowed to change a byte at will you would be able to introduce invalid encoding sequences. As to the absense of documentation, maybe it is because this was thought to be self-evident, dunno. _______________________________________________ gtkmm-list mailing list gtkmm-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtkmm-list
