Let me know if there’s a better channel to post this in: I’ve got a

UInt8

encoded byte array that I need to convert to a UTF-8 string, using Kotlin. various things I’ve tried have converted it into the ASCII value “d”, which is the correct value. But I want the UTF-8 string value “100"

How do you know your single character fits in one byte? Your last attempt assumes that, but that's not how UTF-8 works

I do happen to know that what I’ve got fits into one byte. But, yes, my solution is brittle for scenarios where what I get doesn’t fit into a single byte.

if your byte is not in the range of 0-127, then it is definitely not valid UTF-8 on its own

thanks and keep the comments coming! (I’m taking notes)

even if you use

String.codePointAt(0)

you'll have to decide whether that's actually what you want or if you want to deal with normalization forms, combining sequences, emoji modifier sequences, flags, etc.
