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?

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.]

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.
