According to your mail https://lists.gnu.org/archive/html/bug-libunistring/2023-11/msg00000.html char32_t is less portable, and indeed, the solaris automatic build sees to fail because of char32_t is not available, while uint32_t and ucs4_t are necessarily present with libunistring unless I issed something. So it would probably be more portable to use uint32_t/ucs4_t, though it may be less practical if a conversion is needed before they can be used. -- Pat
