Subject Re: Possible addition to StringUtils
Date Mon, 10 Dec 2001 22:32:17 GMT
Wouldn't B always be escaped with \ since its java's escaping we're worring
about at this point?

What if the following was supplied instead (slightly modified):

Character A to be escape. Possibly a list of characters.
A corresponding Character B to put in front of escaped character A.

     A = {"'", "t", 'b'}
     B = {"'","\","\"}
