Does it give you a reason? Being npc/race names within the game, perhaps they are filtered out as unusable?
They have never allowed you to add a ' to surnames, long ago, you could get a GM to make your surname have one. Same with 2 capital letters in a name.
- The surname command now allows the use of a second capital letter and a single accent character. That has only happened on Test server so far. It will make it to live on the next full patch. https://forums.daybreakgames.com/eq...3-03-2020-patch-notes-and-discussions.263626/
