Can Send Empty Chat Messages

[codergautam (gautam)]

Hi, there is a bug with Chat that allows you to send empty messages which only contain spaces. I have looked through settings but cannot find anything that would help me. Thanks

Legit… this is an oversight and certainly looks odd… we should ban “blank” both server side and client side.

Blank is a tricky animal

Adding text between <> characters renders an empty post. (Example in this post)

When we have seen the same issue, we simply fence them with MD. <here is the good stuff> <here is the sweet stuff> ```<here is the good stuff>``` `<here is the sweet stuff>`

Khmer Unicode Zero Width Space disappears after posting

Hi there, I just installed discourse and found out that it didn’t support Zero Width Space at all. It is Khmer Unicode special character that represents a hidden space to separate each word. you can take a look here http://www.askcambodia.org/t/angelababy/21

lib/text_cleaner.rb

Recommend we just use our text cleaner here server side as well to ensure people don’t cheat themselves as well.
