It's there: <http://www.gnu.org/software/libunistring/manual/libunistring.html#unistr_002eh> "The following function compares two Unicode strings of possibly different lengths. — Function: int u8_cmp2 (const uint8_t *s1, size_t n1, const uint8_t *s2, size_t n2) — Function: int u16_cmp2 (const uint16_t *s1, size_t n1, const uint16_t *s2, size_t n2) — Function: int u32_cmp2 (const uint32_t *s1, size_t n1, const uint32_t *s2, size_t n2) Compares s1 and s2, lexicographically. Returns a negative value if s1 compares smaller than s2, a positive value if s1 compares larger than s2, or 0 if they compare equal." I wonder whether it respects languages. I don't think so, but I can live without it. Time to hack up an external function for SQLite and see how little of the library I need to make it work.
