- should be allowed in name creation

[Lambdafish]

Tbh, I can see this being an oversight that is difficult/low priority to change. The main reason that characters like ' (like in Khuja'to) are present in character name creation is because they exist within eorzea naming conventions, it may be possible that we could get this in the future with a playable race who's naming convention involves "-" characters (as with french naming conventions), though it is unlikely we will see this otherwise.
