--- Comment #4 from Gopala Krishna Koduri gopal.iiit@gmail.com --- It will be useful to include all three of them: punctuation marks, numerals and basic alphabet. At least in Latex, we have to resort to a strange fix to deal with it: http://tex.stackexchange.com/questions/60709/change-the-font-of-hyphenchar/6...
But of course, puncuation marks and numerals have higher priority.
