Hi; how do make certain that no input (keyboard + mouse paste) is outside of 7-bit ASCII in a perl script?
Since I have no intention of correctly or completely handling input that is outside of 7-bit ASCII, I thought it would be best to prevent any characters outside of 7-bit ASCII from being input. How best to do this? I want to keep it simple. Are there specific pragmas and/or modules that I can use to force this? I'm looking at Programming Perl (3rd Edition), Perl Cookbook (2nd Edition), cpan.org, etc, and I'm finding lots of stuff but it is either too much (need some guidance) or not quite what I'm looking for (confusing). Let's say that I have only two kinds of prompted input:Yes/No question and one numeric capturing regex. If I compare the first letter of the response being either "Y" or "y" then I can assume that any other response was a negative, even if it was a 16-bit Unicode character? Secondly, if I literally compare against digits and whitespace in my capturing numeric regex, then anything outside of that I can categorically reject? Looking for the fishing pole more than the fish.
