💖 GRAPHEME_IS_TITLECASE_UTF8(3) — the manual, but make it make sense 💖

okay bestie, so this is from the grapheme library (yes, the manual page header literally says GRAPHEME_IS_TITLECASE_UT(3) — a little typo moment, we move), and it's all about checking whether your UTF-8 string is giving titlecase energy. let's get into it ✨

🌸 NAME 🌸

grapheme_is_titlecase_utf8 — check if a UTF-8-encoded string is titlecase, no cap 💅

🦋 SYNOPSIS 🦋

#include <grapheme.h>

size_t
grapheme_is_titlecase_utf8(const char *str, size_t len,
    size_t *caselen);

✨ DESCRIPTION ✨

so the grapheme_is_titlecase_utf8() function checks if the UTF-8-encoded string str is titlecase, and it writes the length of the matching titlecase-sequence to the integer pointed to by caselen — unless caselen is set to NULL, in which case it just doesn't do that part, periodt 🫶

if len is set to SIZE_MAX (and heads up: stdint.h is already included by grapheme.h, so you're covered 😌), then the UTF-8-encoded string src is interpreted to be NUL-terminated, and processing stops when a NUL-byte is encountered. like it just knows when to stop, main character energy fr fr 💀

for non-UTF-8 input data, you can use grapheme_is_titlecase(3) instead — that's your girl for the other encodings 🌈

👑 RETURN VALUES 👑

the grapheme_is_titlecase_utf8() function returns true if the UTF-8-encoded string str is titlecase, otherwise false. simple as that, slay 💅

🎀 SEE ALSO 🎀

⭐ STANDARDS ⭐

grapheme_is_titlecase_utf8() is compliant with the Unicode 17.0.0 specification. iconic behavior, honestly 🔥
