ive seen several implementations which use mbtowc functions to test some special chars, this is not correct for utf 8 in my opinion.
To count the number of UTF-8 characters is really simple, just count all bytes except those with value in range 0x80 to 0xBF. This has two exceptions 0xFE and 0xFF which are no official UTF-8 characters, but I think it's not wrong to count and behave as such.
counting can be done with one logical an one compare instruction: if ((c ^ 0x40) < 0xC0) n++ _______________________________________________ busybox mailing list busybox@busybox.net http://lists.busybox.net/mailman/listinfo/busybox
