+ I found a workaround for my particular situation ... When using the following 
+ logic:
+ 
+ //Match ASCII 32 through ASCII 127, plus ASCII 10 and ASCII 13
+ String DEFAULT_KEYBOARD_FILTER = "^[\\x20-\\x7F\\x0A\\x0D]*$";
+ RE regExp = new RE(DEFAULT_KEYBOARD_FILTER);
+ //if it DOESN'T match, then throw
+ if(!regExp.match(testVal))
+ 	throw new FieldValidationException(fieldNamePretty + " can not contain 
+ special characters.");
+ 
+ i would recive a StackOverflowError with a string of 2 or 3 kilobytes ... 
+ However, by using the inverse expression logic:
+ 
+ String DEFAULT_KEYBOARD_FILTER = "[^\\x20-\\x7F\\x0A\\x0D]";
+ //if it DOES match, then throw
+ if(regExp.match(testVal))
+ 	throw new FieldValidationException(fieldNamePretty + " can not contain 
+ special characters.");
+ 
+ everything went smoothly ... so ... that's my 2 cents .. :)
