/* In GNU libc the conversion functions only can convert between the
fixed wide character representation and the multibyte
representation of the same character set. Since we use ISO 10646
in UCS4 encoding for wide characters the best solution for
multibyte characters is the UTF8 encoding. I.e., the only state
information is a counter of the processed bytes so far and the
value collected so far. Especially, we don't have different shift
states. */
