Context

I was trying to add emojis support on my terminal editor when I faced something that I think might be an issue for the grapheme_count reported width for complex emojis like "🏳️‍🌈".

Odin: dev-2025-11:e5153a937
OS: NixOS 25.11 (Xantusia), Linux 6.17.7
CPU: AMD Ryzen 9 5950X 16-Core Processor
RAM: 32008 MiB
Backend: LLVM 20.1.8

Expected Behavior

I was expecting the result 1, 4, 2 for respectively graphemes, runes, width.

Current Behavior

I got 1, 4, 1.

It seems for be the same for decode_grapheme_clusters.
For the decode_grapheme_iterate it seems to be a bit different, the reported grapheme seems wrong, but if you check the last_... in the iterator struct you get (I think) the right values.

Thank you.
