I got sent a link insinde the latest Teamspeak 5 beta 74. The link is: “https://de.wikipedia.org/wiki/Geschoss_(Architektur)” and the closing bracket is not recognized as part of the URL and i only get “https://de.wikipedia.org/wiki/Geschoss_(Architektur” if i click on it in the chat
I moved the topic back to an individual report.
Due the current regexp we use to identify if ( ) was around an URL or simple text we fail to capture it at the end of an URL.
I forwarded this to our devs but can’t promise a fix.
The link you got was from a TS3 client. The client shows what a TS3 client would hide from a TS3 user.
Whatever was send did break in the TS3 client or user changed part of the URL.
Edit: will evaluate tomorrow what happens in TS5 when it was send and received from there.
Dont worry about it getting fixed. I just noticed it and wanted to report it so its known and maybe someone finds the time to fix it.
Thanks for your time 
Good news. We may have found a good regex.
Example from @diegoperini only fails in 2 cases
