* Goal: prefer color emoji fonts when available, without changing existing
* font size/style/weight, and without breaking user-configured fonts.
*
* Pango already routes emoji presentation runs to a color emoji font on its
* own, so the base font must NOT list an emoji family explicitly: doing so
* hands the emoji font every character its cmap covers, including '#', '*',
* digits and adjacent spaces (keycap components), which then render with
* wide emoji metrics ("/join #" grows a huge gap in the input box). Only
* Windows 7, which has no color emoji font for Pango to find, gets an
* explicit fallback family appended.
