The restriction to word chars in abbrevs as removed a long time ago.
Really? That should be known.
It is known.

It's known you delivered some code WRT that purpose.
It never worked here. Seems other faced some difficulties too:


So https://debbugs.gnu.org/cgi/bugreport.cgi?bug=15485 is fixed?
No, but I'm not sure it's a bug.  It's the way `add-abbrev` works.
The abbrev-tables themselves don't have that restriction.

So what does abbrev--check-chars inside define-mode-abbrev?:

        (error "Some abbrev characters (%s) are not word constituents %s"

A related issue later on:

  (define-abbrev local-abbrev-table (downcase abbrev) expansion))

If everything is downcased, expansion can't distinguish the original case.
