in thread Special character not being captured

DATA is the handle used by Perl to read the source file. As a result, use utf8; affects not just the source file, but DATA as well. Specifically, it adds a :utf8 layer to DATA. Since DATA already has a :utf8 layer, so adding :encoding(UTF-8) is incorrect (though harmless).

Furthermore, use open ':std', ':encoding(UTF-8)'; adds :encoding(UTF-8) to not just STDOUT, but also to STDIN and STDERR. (It also causes instances of open in scope to add that layer by default.) And it does so a compile-time. This is usually the better route.

#!/usr/bin/perl use warnings; use strict; use feature qw{ say }; use utf8; use open ':std', ':encoding(UTF-8)'; say substr('Ĉon Flux', 0, 1); say substr <DATA>, 0, 1; __DATA__ Ĉon Flux

    I'm not using the DATA handle. The strings the get passed to first_alpha come from hashes most of the time. I asked earlier in this thread, but do I need to post the entire process that lead to the problem with this one character not being "seen" properly by first_alpha?

    No matter how hysterical I get, my problems are not time sensitive. So, relax, have a cookie, and a very nice day!
