FcUtf16Len(3)

okay so welcome to the FcUtf16Len page from the fontconfig manual, bestie 💅✨ this one is short and sweet and it’s all about counting UTF-16 encoded chars, no cap 🦋

🎀 NAME 🎀

FcUtf16Len — count UTF-16 encoded chars. that’s literally the whole name and honestly it ate 💅

---

✨ SYNOPSIS ✨

include this header and call it like so, bestie:

#include <fontconfig/fontconfig.h>

FcBool FcUtf16Len (FcChar8 *src, FcEndian endian, int len, int *nchar, int *wchar);

---

🌸 DESCRIPTION 🌸

okay so here’s the tea: FcUtf16Len counts the number of Unicode chars in len bytes of src. Bytes of src are combined into 16-bit units according to endian. 🫶

the count gets placed in nchar ✨

and wchar contains 1, 2 or 4 depending on the number of bytes needed to hold the largest Unicode char counted 👑

the FcBool return value indicates whether string is a well-formed UTF16 string — it’s giving vibe check for UTF16, fr fr 💖

here’s the parameter lineup so nobody gets confused 😭

• src — the bytes we’re looking at; we count Unicode chars in len bytes of it.
• endian — decides how bytes of src get combined into 16-bit units.
• len — how many bytes of src we’re counting.
• nchar — where that count gets placed.
• wchar — contains 1, 2 or 4 depending on the number of bytes needed to hold the largest Unicode char counted.
