Another more rich API we could immediately put to good use is the ICU strcoll() variant that does not require NUL-terminated strings: https://ssl.icu-project.org/apiref/icu4c/ucol_8h.html#a3abc6779e6452106415918199308fab4 We do not use a NUL byte for terminating text data, and so must copy its contents into a temp buffer, or array on the stack, all rather inefficiently. Robert has expressed an interest in an API like this strcoll() variant in the past [1], to avoid this unnecessary overhead.
