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