Before you paste one into your server name
Not every symbol survives every client and font. Test it with the status checker and look at what actually comes back, rather than trusting how it looks in your editor.
Symbols in a server name make it stand out in a long list, but a name that is mostly decoration is harder to search for and harder to recommend. One or two is usually enough.
