WalkthroughEmoji data now comes from generated modules with legacy shortcode fallback. Emoji search ranks aliases and names. Composer backspace handling removes complete Unicode emoji glyphs. ChangesEmoji data and alias lookup
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to Emoji rendering and picker aliases are corrected, but backspace handling can still misbehave for certain tag-flag and regional-indicator emoji sequences by leaving invisible characters or deleting too much text. This is a bounded correctness risk that is mergeable with explicit owner awareness and follow-up. Suggested labels: Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

Line 157 contains a literal U+FE0F inside the regex. The character is invisible in the source. An editor, a copy-paste, or a formatter can remove it without any visible change, and
bare()then stops stripping the variation selector. The legacy fold at line 174 depends onbare(), so the failure is silent.Use the escape sequence instead.

- Around line 20-28: Update the test around aliasesByEmojiName to compare each
alias’s resolved Unicode with its owning emoji name’s resolved Unicode, rather
than only checking that the alias resolves. Apply the same
variation-selector-insensitive normalization used by the generator so equivalent
forms such as ⚠️ and ⚠ are treated as equal, and keep mismatched owners in the
existing assertion result.

Blocker — the PR description contradicts the tree
The generation approach is the right call: deleting a hand-maintained 4,600-line map in favour of a script over emojibase-data, split into generated data.ts / hand-maintained legacyShortnames.ts, is a genuine simplification. Tests pass (26/26). Two things block it.
The description says "Merged the joypixels + emojibase shortcodes … as aliases (3,171 names). No existing value changed." and "Left out … man_in_tuxedo_tone1–tone5, which changed meaning upstream — kept legacy so old messages don't shift."
Measured against develop:
- 347 shortnames changed value. 333 are FE0F-only (presentation sequence); 14 are real glyph changes.
man_in_tuxedoandman_in_tuxedo_tone1–tone5did change (🤵 → 🤵♂️) — the exact six the description says were held back.beetle: 🐞 → 🪲. A semantic change to an existing emoji, unrelated to the bug being fixed. Every stored:beetle:reaction and message flips glyph on upgrade.- Picker: 1,406 → 1,914 listed. 582 added, 74 dropped (
cop,spy,walking,runner,dancers,bride_with_veil,iphone,face_palm,shrug, …) — they still resolve, they just vanish from the picker.
The good news, and it's the hard part: 0 shortnames that used to resolve now fail. legacyShortnames.ts genuinely covers every removal.
But a reviewer or QA reading the current description will test the wrong things. Please rewrite it to describe the regeneration, and state the value-change count and the beetle / man_in_tuxedo shifts explicitly as accepted consequences.
Remaining findings are inline. #1 above and the pin gap on useShortnameToUnicode/index.tsx are the two that matter; the rest is mechanical cleanup.

- Around line 47-52: Update the regional-indicator handling in lastGlyphLength
so it counts the contiguous regional-indicator run before the final code point
and adds the preceding indicator’s size only when that run length is even;
preserve separate-glyph behavior for odd-length runs such as three indicators.
- Around line 8-12: Update isAttachedToWhatPrecedesIt to treat Unicode emoji tag
code points from U+E0020 through U+E007F as attached characters, so backspace
removes the complete emoji tag sequence as one glyph; add a regression test

27-27: Keep the variation selector escaped.This line embeds an invisible U+FE0F character. If an editor or formatter changes it,
bare()can stop removing variation selectors. Legacy folding can then assign aliases to different entries. Use/\uFE0F/g.
45-95: Restore comments for the order-dependent rules.The change removes the explanation for first-write precedence and for excluding regional indicators and tone variants. These rules affect generated alias ownership and component handling. Restore short comments that state why the ordering and exclusions are required.

Proposed changes
Emojis sent from web render as raw text on mobile —
:water_wave:instead of 🌊.Web dropped emojione in #39411 and now reads shortcodes from emojibase-data, resolving
joypixels ?? emojibaseingenerateEmojiData.ts.Those sets name 🌊 both
oceanandwater_wave. Our map comes from the iamcal set, which knows onlyocean— so the lookup misses and we render the raw text.useShortnameToUnicode/emojis.tsas aliases(3,171 names). No existing value changed.
men_wrestling,women_wrestling,kiss_mm,kiss_ww,kiss_woman_man,couplekiss_mm,couplekiss_ww.app/lib/methods/helpers/emojiAliases.ts), sowater_wavefinds the picker's
ocean.Left out: the
cldrpreset, which web doesn't use, andman_in_tuxedo_tone1–tone5, whichchanged meaning upstream (🤵 → 🤵) — kept legacy so old messages don't shift, same call as
#41587.
