 > I'm curious how you encountered this issue? Would there be other hyphen-
 like characters which would be suitable for turning into hyphens?

 I encountered the issue when a user used the non-breaking hyphen in their
 post title. The non-breaking hyphen was used within a hyphenated product
 name which I assume they didn't want broken between lines. I'm guessing
 they copied it from some sort of marketing material but I'm not really
 sure.

 As far as other hyphens go, I don't know if I have the knowlege to answer
 that question. I see 13 different characters listed under
 [https://www.compart.com/en/unicode/category/Pd dash punctuation] and I'm
 hesitant to broaden the scope of this fix unecessarily without knowing
 which dashes are common enough to be covered. If you have insight into
 this feel free to suggest or make any changes.
