BSON_UTF8_FROM_UNICHAR(3)

💅 BSON_UTF8_FROM_UNICHAR(3) — the libbson one, bestie ✨

okay so picture this: you're deep in libbson land and you've got exactly one unicode character that needs to become UTF-8. yeah. that's the whole vibe of this page. sit down, grab a strawberry 🍓, let's go.

🌈 SYNOPSIS 🌈

void
bson_utf8_from_unichar (bson_unichar_t unichar, char utf8[6], uint32_t *len);

literally the entire function. no drama, no return value, just vibes and output params.

---

🎀 PARAMETERS 🎀

• unichar — a bson_unichar_t. this is the one (1) unicode character you're converting. main character energy fr fr 👑
• utf8 — a location for the utf8 sequence. this is where the magic gets written. it's a char array sized 6, so there's room to breathe 🦋
• len — a location for the number of bytes in the resulting utf8 sequence. you hand it a pointer, it tells you how many bytes got used. no cap, that's it 💅

---

✨ DESCRIPTION ✨

so here's the tea ☕: this function converts a single unicode character into a multi-byte UTF-8 sequence. iconic behavior honestly.

the result is stored in utf8 and the number of bytes used goes into len. that's the whole trick — character in, bytes out, count reported. periodt. 🫶

ngl bestie, utf8 has to have room for 6 chars in the synopsis, and len must be a valid location — pass real pointers, don't be messy 🙈
