✨ pr29_4 ✨

okay bestie, gather round, because we're talking about pr29_4, a lil function from libidn that is lowkey doing the most important detective work in the whole Unicode universe 💅

🌸 NAME 🌸

pr29_4 — it's an API function, bestie, that's literally the whole name 🎀

🦋 SYNOPSIS 🦋

#include <pr29.h>

int pr29_4(const uint32_t * in, size_t len);

💖 ARGUMENTS 💖

  • const uint32_t * in — the input array, and it's stuffed with unicode code points 👑 like, that's its whole personality.
  • size_t len — the length of that input array, aka how many unicode code points we're working with here. just the count, nothing extra ✨

🌈 DESCRIPTION 🌈

so here's the vibe check: this function looks at your input and asks the big question — could different NFKC implementations normalize this exact same input into different strings?? 😭 because of an anomaly in the NFKC specifications, yes, that's a real thing that happens, and it's giving chaos fr fr 💀

Return value: it hands you back a Pr29_rc value — PR29_SUCCESS when everything's chill and fine 🌸, and PR29_PROBLEM if your input sequence is a "problem sequence" 🚨 which means it may get normalized into different strings by different implementations. not to be dramatic but that's the whole plot twist, no cap.
