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
When we have seen the same issue, we simply fence them with MD.

```<here is the good stuff>```

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
@@whitespaces_regexp =
Regexp.new(
"(\u00A0|\u1680|\u180E|[\u2000-\u200A]|\u2028|\u2029|\u202F|\u205F|\u3000)",
Regexp::IGNORECASE,
).freeze
def self.normalize_whitespaces(text)
text&.gsub(@@whitespaces_regexp, " ")
end
Recommend we just use our text cleaner here server side as well to ensure people don’t cheat themselves as well.

We have fixed this in this commit:
committed 06:06AM - 08 Jun 23 UTC
This fixes an issue where a user could send an empty
string as a chat message .… e.g ' ' and the message would
be posted. We don't want this, we need to strip the message
first before validating for length etc.
Thanks!
