uwidth(3alleg4)

✨ NAME ✨

okay so bestie, this is uwidth from the Allegro manual (that's the 3alleg4 section, iykyk) — it's a low level helper function for testing Unicode text data. it also lives in the Allegro game programming library, so yeah, it's giving gamedev Unicode energy 💖

🌸 SYNOPSIS 🌸

#include <allegro.h>

int uwidth(const char *s);

🦋 DESCRIPTION 🦋

low level helper function for testing Unicode text data. that's literally the whole vibe — it's a lil baby utility that hangs out down in the weeds so the higher-level Unicode stuff can do its thing 🫶

💅 RETURN VALUE 💅

it returns the number of bytes occupied by the first character of the string you passed in, measured in the current encoding format. so like, not the whole string, bestie — just the first character, and in bytes, not characters. slay ✨

heads up: "current encoding format" is doing a lot of heavy lifting in that sentence, so if the numbers look weird to you, check what encoding you're actually in before you spiral 😭
