I crossed a post that has close parenthesis symbol aka ")" in URL links, specifically it's related to Bisq. I thought the forum ban this link, but after I made some research to find other URL link with close parenthesis symbol, the results is same...
You mean link with parenthesis are ban here? Or just bisq url?
I don't think its a bug, it depends on the machine software used by the forum if those symbol can be used for URLs or they will be automatically encoded, i experienced this while developing websites.
