Have Linter Catch Unusual Characters in Symbol/Keyword Names?

[jcburley]

I just noticed this on the #clojure channel on Slack; seems like detecting e.g. (ns a–b), which has an em dash, as problematic (versus (ns a-b), which uses a normal dash) might be useful:

I fat fingered with compose-keys turned on, and accidentally discovered that if the ns name in the ns form has an em-dash instead of a dash, require returns without error but it creates a broken namespace. of course the answer is "don't use em-dash in the namespace symbol", but I wonder if there's a linter that checks for things like that

Certainly sounds like a linter that checks for strict ASCII subset (for some fraction of developers), or a larger set that includes other alphabets could find this quickly.
