But in my case this is not possible as the system that I am writing the regex does not support the split function or join it only supports C format commands syntax, so I am using Perl as a test tool before implementation.

Does the system you're on (which one - PCRE?) support search and replace?

my $sample = "041424344454647484940414";
(my $output = $sample) =~ s/.\K.//g;  # alternative s/(.)./$1/g;
die $output unless $output eq "012345678901";
