Chat models often emit GitHub/Slack-style :shortcode: text (e.g. 😊,
🎤) instead of the actual emoji. The renderer only converted real
Unicode emoji to the monochrome line icons, so shortcodes rendered as literal
text.
Add a pure, browser-free shortcode->Unicode map (emojiShortcodes.js) and run it
inside svgifyEmoji ahead of the existing Unicode->SVG pass, skipping <code>/<pre>
so code stays literal. Covers ~430 common shortcodes plus common aliases
(+1/thumbsup, etc.).
Keep the conversion from touching anything it shouldn't:
* Scope it to chat. mdToHtml/svgifyEmoji take a { shortcodes } option (default
on); document and email body rendering (compose, export, preview) pass it as
false so author-typed :shortcode: text stays literal. The Unicode->SVG pass
still runs there exactly as before.
* Only convert a :shortcode: that stands on its own. A word-boundary guard
leaves embedded colon runs alone, so "1:100:2", "10:30:45", "16:9" and
host:fire:port are never rewritten.
Tests: extend the node-driven unit test with the boundary/false-positive cases,
and fix the markdown-rendering test loader to resolve the new emojiShortcodes
import.
