Overview ¶
emojiwidth is a one-shot diagnostic that asks your terminal how many cells it actually advances the cursor for a handful of emoji glyphs. Run when fv-go renders with stray gaps or overflow on emoji-heavy rows — the report tells you which codepoints disagree between fv-go's UAX#11 width tables and your terminal's real rendering.
Usage:
go run ./cmd/emojiwidth
Must be run in an interactive terminal — it uses CSI 6n (Device Status Report) to ask the terminal where the cursor is before and after printing each glyph.
