I've been using Perl (5.18.2) with PurePerl in a chroot to manipulate UTF-8 text files containing accents for a few years. I just recently decided to bring my code into a more modern setting (5.26.1) so that I could more easily invite collaborators. I'm not receiving any error messages, but now I'm getting blank lines instead of my previous output. How should I begin debugging what I think to be parsing or encoding problems? I checked the encoding and it appears to match in both the chroot and the new environment. The PurePerl mod installed in the new environment with no errors.
