restricting character set in a Textinput field

apache-flex mxml character textinput restrict

I have a TextInput field that should be restricted to either capital letters, lowercase letters, numbers and underscores. This is the code I'm trying to use to restrict characters:

restrict="\\A-Z\\a-z\\0-9\\ \\_\\-"

I'm using MXML for this Textinput component.

Unfortunately this does not restrict the \ character, which is the last character I'd like to restrict.

How can I add the backslash to the list of restricted characters?

Thanks

Stephen

Actually found the solution I've amended the restrict code to:

restrict="A-Za-z0-9 _\-"

I took out all the back slashes which I thought or was using as delimiters.

Works fine now.
