in reply to Special characters in perl/cgi

HTML::Entities also allows you to supply your own character mapping, something I have found very useful. If you look at the source code of that module you will see how to build the map. See also the chr() and ord() functions for another way to represent these characters in Perl. BTW not escaping HTML tags like <H1> can seriously break your form.

[jdporter]: one prog I have has a UI which allows to input a bit mask
[jdporter]: currently it expects the bitmask to be in the form of a hex number, e.g. 0x0101
[jdporter]: but I'd like to let the user specify it as individual bits, i.e. 0b0000000100000001
[jdporter]: there is no bit/binary equivalent of hex, right?
[jdporter]: I guess that the most direct way of doing it is with some magical incantation involving unpack or whatever
[jdporter]: let me google that for me ;-)
[jdporter]: hex points explicitly to oct, which does the job. :-D
[jdporter]: omg, I f love Perl!
[choroba]: say unpack 'H*', pack 'B*', $mask =~ /0b([01]+)/;
