Regarding your original question of why you need \\ for escaping "-" or "^", this is because they are special characters, that must be escaped with "\". Now, it seems that the compiler will also interpret "\" in static string as escape chars, except for \n, \t , \r ... So that might be the reason.
If you can debug, try different variations and trace(RESTRICT_STRING_FOR_CSV) to see what is the exact value.

The restrict test happens in mx.util.StringUtil. testCharacter() The restrict sequence is parsed for each typed char. I am currently looking at the code. You might also have a look at it, if you have something ..

I found by experimentation that the following works, public static const RESTRICT_STRING_FOR_CSV:String = "0-9 a-zA-Z\&\"'~!@#$%*()\\-_+=[]|;:<>.?,\\^{}"; which uses ONE backslash to escape the ampersand and double-quote characters, but TWO backslashes to escape the minus sign (e.g. \\-) and the caret (e.g. \\^). However, I can't seem to figure how to escape the backslash character (I tried \\ and \\\ and neither worked). Is this making sense to anyone? Any idea how to escape backslash? ----- Original Message ----- From: [email protected] To: [email protected] Sent: Thursday, March 6, 2014 9:02:07 AM Subject: Re: how to mxml restrict with binding AS3 variable? Setting textInput.restrict=... in creation complete didn't change anything. There must be some difference or interaction between escape characters written in AS3 working in mxml. I need a programmatic solution, as there are so many places I can't manually write mxml code for each restrict. Any ideas? [Alex: not sure what you meant by "trace out the restrict property..." -- I'm testing by manually entering the characters in the text input field and seeing which ones work and which ones don't.] ----- Original Message ----- From: "Alex Harui" <[email protected]> To: [email protected] Sent: Thursday, March 6, 2014 8:33:07 AM Subject: Re: how to mxml restrict with binding AS3 variable? Don't use binding, set it directly in creationComplete/applicationComplete and see if you still have a problem. If so, trace out the restrict property from the TextInput to see if got modified somehow.
