Hum, it seems interesting. I would like to take a look at that. :-)


But before, I will continue to read and clean code.

I wonder whether the use of strlen() on UTF-8 is correct, it
shouldn't... If I remember correctly, unicode can use arrays filled that
way:
'\0' 'H' '\0' 'E' '\0' 'L' '\0' L '\0' 'O'      ("HELLO")
where a '\0' can be replaced by a value to stock characters on 2 bytes.
But I don't remember if it happens with UTF-8. I'll have to check what
happen with strlen() and funky characters.
strlen() counts number of characters that precede a null byte.
In Glib, there are functions like: g_utf8_strlen(), g_utf8_strncpy(),
g_utf8_strchr(), etc.
