"how to make this conditional, either hyphen (-) or I want to say en dash(–)?"
Just replace the single hyphen in your regex with a character class containing all possible dashes, hyphens, etc. In the character class, always put an ASCII hyphen as the last character or you'll generate a range. See perlrecharclass and, in particular, the "Bracketed Character Classes" section for much more detailed information.
An example script follows but, first, some notes:
#!/usr/bin/env perl use strict; use warnings; use open OUT => qw{:encoding(UTF-8) :std}; my ($en_dash, $em_dash) = ("\x{2013}", "\N{EM DASH}"); my $str = "a-b${en_dash}c${em_dash}d"; my $re = qr{[\N{EN DASH}\x{2014}-]}; print "Original string: $str\n"; print "Parts separated by some dash:\n"; print "$_\n" for split $re, $str;
Output:
Original string: a-b–c—d Parts separated by some dash: a b c d
Because the hyphen and dashes are not easily distinguishable, here's the same output piped through cat -vet. Don't worry too much if you don't understand the codes; just notice that they are different.
$ ./pm_11137036_re_alt_dashes.pl | cat -vet Original string: a-bM-bM-^@M-^ScM-bM-^@M-^Td$ Parts separated by some dash:$ a$ b$ c$ d$
