FcUtf8Len(3)

🌸 NAME 🌸

okay bestie, welcome to FcUtf8Len(3) — the page that literally counts UTF-8 encoded chars, no cap 💅.

---

🎀 SYNOPSIS 🎀

#include <fontconfig/fontconfig.h>

FcBool FcUtf8Len (FcChar8 *src, int len, int *nchar, int *wchar);

---

🦋 DESCRIPTION 🦋

So here’s the vibe: FcUtf8Len counts how many Unicode chars are hanging out in len bytes of src, and it places that count into nchar ✨.

Then wchar gets 1, 2, or 4 — depending on how many bytes are needed to hold the largest Unicode char it counted 👑.

And the return value? It tells you whether src is a well-formed UTF8 string, fr fr 💖.
