FUNCTION::USER_STRING_UTF32(3stap)

✨ NAME ✨

function::user_string_utf32 — bestie, this one retrieves a UTF-32 string straight outta user memory 💖 (yes it's a 3stap page, we're in tapset land now, buckle up 🎀)

---

🌸 SYNOPSIS 🌸

1) user_string_utf32:string(addr:long)

2) user_string_utf32:string(addr:long,err_msg:string)

Like… two whole flavors of the same function. Pick your fighter 💅

---

🦋 ARGUMENTS 🦋

• addr — the user address you're pulling the string from. The main character of this operation, lowkey 🫶
• err_msg — the error message that gets handed back when the data just… isn't available. Your lil safety net, ngl 😭

---

💜 DESCRIPTION 💜

1) okay so this one returns a null terminated UTF-8 string that's been converted from the UTF-32 string sitting at a given user memory address. And if the string copy faults out or the conversion goes sideways? It reports an error. No cap, that's the whole vibe check 🔥

2) same deal — returns a null terminated UTF-8 string converted from the UTF-32 string at a given user memory address. But this time, on a string copy fault or a conversion error, it reports the error message you gave it. Custom error messages are so iconic, honestly 👑

heads up bestie: both versions can fail — one yells generically, one yells with your words. Either way, a fault or a conversion error is a fault or a conversion error, periodt 💀
