💖 stringprep_ucs4_nfkc_normalize(3) 💖

okay bestie, sit down, hydrate, and let me tell you about a little function from libidn that is lowkey doing the most important glow-up work in the whole Unicode friend group: stringprep_ucs4_nfkc_normalize(3). it takes your messy UCS4 string and gives it the canonical-form makeover. no cap. ✨

🌸 NAME 🌸

stringprep_ucs4_nfkc_normalize — literally the API function, that's the name, that's the vibe 🫶

✨ SYNOPSIS ✨

#include <stringprep.h>

uint32_t * stringprep_ucs4_nfkc_normalize(const uint32_t * str, ssize_t
len);

🎀 ARGUMENTS 🎀

  • const uint32_t * str — a Unicode string, bestie. it's const, so hands off, we're just looking 👀
  • ssize_t len — the length of the str array, or -1 if str is nul-terminated. like, if you already ended it with a nul, just say -1 and we'll figure it out ourselves, we got you 💅

🦋 DESCRIPTION 🦋

Converts a UCS4 string into canonical form. the way that it does this… iconic. for more info, go check out stringprep_utf8_nfkc_normalize() — same energy, different encoding, iykyk.

Return value: a newly allocated Unicode string, and that string is the NFKC normalized form of str. it's giving fresh-out-the-box, brand new, all yours to free later (not that we're saying it out loud but like, you know 🔥).
