gkbd-keyboard-display: better info for ellipsized or numerically-bound symbols
When a symbol renders in gkbd-keyboard-display with its unicode number (e.g. U+202A
or with a symbol too wide to view (i.e. when it is "ellipsized") the user is left in the dark.
It'd be nice to offer some mechanism that an interested user can use to learn more about such a mystery symbol.
It might also be nice for non-ellipsized symbols: maybe someone wants to know that A
is U+0041 LATIN CAPITAL LETTER A
for that matter, especially for symbols with visually-indistinguishable glyphs.
