unstack chat breaks name highlight

[ChillerDragon]

The ddnet client requires a space before the hilite match or it has to be the beginning of the line. So putting a unicode character without space in front breaks the highlight.

Putting the unicode at the end breaks the unstack feature.

Prefixing the name with a space would make it visible to the user that there is some offset.

Relevant client code:

https://github.com/ddnet/ddnet/blob/b34edb64c0a20373214bdc28d666ba445f43263d/src/game/client/components/chat.cpp#L559

The nicest for the user but CPU expensive for the server solution i see is the following: If the prefix symbol is not empty (yes sometimes its none) and the message starts with a string that is a name of a connected player then also insert a space after the unicode character.

It now looks like this. And always pings. But there is a visible space if it starts with a player name.
