Custom Nameplates only match player Unit names with exact (case-sensitive) names, and not with the * wildcard or any UnitId

Use case is setting Friendly nameplates to Headline view in arena using wildcard matches, to apply the Arena Friendly Markers weakaura while maintaining Healthbar view in the open world.

Interesting, I'll try to find out why this is happening.

That is already possible right now - although at least the German translation misses that part. Here's the help text for trigger by name: Apply these custom settings to the nameplate of a unit with a particular name or NPC ID. You can add multiple entries separated by a semicolon. You can use use * as wildcard character in names.

And that still works, I just tested it.

Interesting, I'm using v12.0.9 and get the below results changing to headline with no icon:

Ruga* or any variation does not match players, the only thing that will match the player is Rugaard (case-sensitive)

So, I can verify that "*" works on some player units, but not all of them. Not sure why yet.

Wildcards are actually only applied to NPCs, not to players. That's why it does not work currently. I guess when implementing it I thought that no one would use wildcards for players, so I added a condition for NPCs.
