Fixed soft hyphen

Invisible character in a thread title​

One of my members just posted a thread with an invisible character, we are running XenForo 1.1.0 Beta 5 Released.
The thread was impossible to access without modifying the thread title to something clickable.
Once I asked about this from him, he told me the following.

Thread title was one character -> http://encyclopediadramatica.ch/Alt-0173
Thread message was a mere [QUOTE tag][/QUOTE tag]

Perhaps something should be done to this to prevent it from happening in the future.

Shouldn't be too hard to fix that.

Title and picture say enough

 

[Paul B]

That's the bug....

The bug is it's possible to post a title using an invisible character.

Ohh I just noticed it's a duplicate

Merged with the original thread.

The character is a soft hyphen. I'm going to start removing it as it is a very rare character, though it has some potential uses.

I should note that in terms of a general purpose thing, there are lots of characters that can cause this and have valid uses, so we can't necessarily strip them out ourselves. You can always get into the thread via any date displayed in the row or you can click edit to change the title on the thread list.
