stray-emoji

An emoji in a file.

Group: Text
Runs: Optional: run it with ur lint --rule stray-emoji
Level: warning
Reads: Every file
Fix: None: the words that replace an emoji are the author's to choose

Why

The line holds an emoji: a character Unicode presents as an emoji by default, or one the emoji variation selector asks to. In code, comments, messages, and output, emoji are decoration an agent adds and a reader skips. Write words. Symbols Unicode presents as text, such as ✓ or →, are not reported. The rule reads every text file, whatever its language, and runs where [lint.stray-emoji] turns it on; a project leaves out data that holds emoji on purpose with its exclude globs.

The fix, as Ur suggests it: say it in words.

For agents

Write no emoji in code, comments, messages, or output; say it in words.
