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