Character>>#isSpecial?

Christoph Thiede

Hi, I'm missing a simple selector.


I would like to check whether a character is a control character like Esc, an arrow or Character insert. Does there currently exist any better solution than testing [aChar asInteger < 32]?


Best,

Christoph

Check out the class methods in #Character in the category "accessing untypeable characters" and see if that will help you write the method you need.
