Since this issue is so common, I wonder if we could add this feature to the
lilypond code base? I thought the requirement is following:
1. The feature should be turned on by default with list of ascii punctuations,
like ",.?{}()! :2. The list of punctuation can be override/customized with any
unicode character list. 3. The feature can be turned off by override/set the
punctuation list to empty.
Is it feasible? If it is ok, I would like to help, but with my limited
lilypond and Scheme knowledge, I wonder If I could make it.
ThanksJun

is the .ly UTF-8 file with test. I also attacha png file for your reference.
Thank you for your help,Ming

Jun, Thank you. I add a few punctuation to your code.
David, I don't know scheme. That's why I did a lousy job. I add few more
punctuation to the Jun's latest code. It works.
Thank you both. I have been looking
this for a long time.
Nice to hear! By the way, did you mean to add the parentheses at "a" and :b"
to your lists?
