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

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.
