Hello,

Since “special characters” means different things to different people and in different contexts, there’s no one answer. The simplest solution is to use a validation expression to identify acceptable characters. A regexp like this:

[a-zA-Z][a-zA-Z0-9 _]*

will allow only spaces and alphanumerics and underscores, but starting with a letter.

Edit: this is part of the FormattedTextField:
