Vim spell punctuation for ⸮ I am finding myself using the point d'irony () more and more. However, vim spelling does not recognise it as a valid punctuation character. How can I add it to vim so that the spelling works?

As umläute suggested in a comment, to Tyler Durden's answer, I opened a feature request/bug report issue 258 in vim. The fix is in patch 7.4.444.
