Zalgo text nicknames obscure parts of chat

[NHAS]

Incorrect boxing of the zalgo text

Two examples of correct boxing.

Description

The zalgo text goes outside of its intended area and can obscure bits of the chat, and potentially the verification UI (although not pictured)

Steps to reproduce

• Use http://www.eeemo.net/ to generate a zalgo text name
• Use /nick to set nickname

This would better be shown as the screenshots of the correct behaviour that exists in chat log, and nicklist.
