Ok, In that case TEXT-93 will take care of what you are thinking. that to
simply expand range and create array of characters however that is little
painful for application developers.
What I'm pushing for is pass just array of (min, max) pairs and API will
take care of it, that will be less painful and easy to use API.
Ex.
char [][] ranges = {{'0','9'},{'A','Z',{'a','z'}}};
RandomStringGenerator generator = new
RandomStringGenerator.Builder()
.withinRange(ranges).build();
