The game doesn't handle special characters very well... I think my family eventually needed a manual fix after it was discovered, many years after creation, that the game was bugging out for a few things relating to it. Realm names like "Fheuv'n" and "D'Hara" also create a few issues here and there.
Best to avoid special characters as much as possible, though I wish the game would better handle such basic characters as apostrophees.
