But not every glyphless character has an acronym, so this is not a
bug.  You are suggesting an enhancement (which is fine).

> First bug + patch:
> Using update-glyphless-char-display to choose to display variation-selectors as acronyms does not work

> The attached patch attempts to fix this and succeeds for U+FE00..U+FE0E but fails for U+FE0F.

Why are the acronyms you propose so long?  Why not use "VS01".."VS16"
instead?  Shorter acronyms are an advantage, since they will be
displayed in a more legible way.

> Second bug:
> It seems that U+FE0F will not at all respect glyphless-char-display, instead always showing as an empty
> box.
> This I have not solved.

Please show a recipe for that starting from "emacs -Q".

Thanks.
