When there are tabs in a username then when you tab complete the username the tabs are included but to ping the username you must omit the tabs.

Note that the reply feature (beginning a message with :<msg number>) still functions normally.

Steps to reproduce

My chat username is

0                                                                                                               '

(Note that while my username contains 28 tabs, one tab is sufficient to cause the problem)

Enter a chatroom such as the sandbox and type @0 into chat. A suggestion will appear for a username that appears to be @0 '. Hit tab. The full username will appear in your chatbox (including the 28 tabs). Send the chat message. I will not be pinged and when hovering over the chat message the username will not be highlighted. Type @0' into a chat message and send it. The username will be properly highlighted and I will be pinged.

    @ShadowWizard This username only has 7-bit ASCII chars (0, 28×\t, '). Tabs are normally considered whitespace, since they get reduced to a single space (\s). In pings, chars that are considered whitespace are supposed to be removed. Unfortunately, here they must be manually removed, while they should be automatically removed (the user is still pingable). – EKons Apr 23 '17 at 8:30

    @ΈρικΚωνσταντόπουλος I never said this is not a bug. Just that it's a bug not worth fixing, as the actual solution is "just don't do that" – Shadow Wizard Apr 23 '17 at 8:35

    @ShadowWizard I think the actual fix is to entirely ban tabs from usernames as "special characters". – EKons Apr 23 '17 at 8:45
