@Jonathan Lamothe We have a pretty lax policy when it comes to hashtags. We accept letters, numbers and special characters including spaces (even though I don't think we match them, but I can see them in the autocompletion from received posts' tags).

We could tighten the accepted range to exclude some characters, but how do you decide which ones?

@Hypolite Petovan I mean, for matching when a post is made, I'd personally stick with alphanumeric (plus perhaps underscore?)

If you want to add other characters, perhaps some kind of notation for deliberately doing that, such as @screwlisp's suggestion here? (which may have been tongue-in-cheek, but...)

or you can have them but they #|Must be enclosed in pipes)|

@Jonathan Lamothe @Hypolite Petovan so what actually would be needed is the regex to exclude all the unwanted characters, like parenthesis or no width space and then whenever we find some character that should terminate a tag we can add it to the regex.

@Hypolite Petovan out of interest, do you know where this is done in the code?
