Originally created by @aaranmcguire on GitHub (Feb 10, 2026).

Originally assigned to: @rekram1-node on GitHub.

Description

While I could upload a pic for the Project icon, I want to change the Project title to be "🦀 Rust Project" and it automatically use the 🦀 as the icon (as it uses the first letter normally). However it just shows an invalid character.

AI describes the issue as:

"🦀"[0] // Returns "\uD83E" (broken - first half of surrogate pair)

Plugins

No response

OpenCode version

1.1.54

Steps to reproduce

  1. Set the Project name to something like "🦀 Rust" or "🙂 Test"

Screenshot and/or share link

Operating System

macOS 26.2

Terminal

@github-actions[bot] commented on GitHub (Feb 10, 2026):

This issue appears to be a duplicate of #12441: Project avatar fallback doesn't support emoji characters, which was recently closed.

Both issues describe the same root cause: JavaScript string indexing returns individual UTF-16 code units, but emojis use surrogate pairs. When using code like [0] to get the first character of an emoji, it returns only the first half of the surrogate pair, resulting in a broken character display.

Since #12441 was already closed, please check if the fix has been deployed or if this remains an open issue.

I created and closed this issues in order to get the eyes by a human (as my assumption is humans only look when bug label is assigned).

I also created a PR, but it was closed as "already supported" when it's clearly not. So I would appreciate a second look.

Traced this to packages/ui/src/components/avatar.tsx:39:

<Show when={src} fallback={split.fallback?.[0]}>

"🦀"[0] returns "\uD83E" (first half of a UTF-16 surrogate pair) instead of the full emoji. Fix is to use Array.from() which splits by Unicode code points:

<Show when={src} fallback={Array.from(split.fallback ?? "")[0]}>

Happy to open a PR if helpful.

I did this PR (which worked): https://github.com/anomalyco/opencode/pull/12442

So you can also try your version and see if they prefer that.
