Perl is not yet fully unicode compatible, despite the fact we will soon ring in the year 2024. Perl's official documents still see security risks with unicode, saying, for example: "Also, the use of Unicode may present security issues that aren't obvious, see 'Security Implications of Unicode' below." There are, however, some ways to get around this. One of those is to include pleas in your own code to use unicode, such as these: 
use utf8;  #FOR THE "wide characters" IN YOUR OWN CODE

binmode STDIN,  ":utf8"; #FOR INCOMING UTF8
binmode STDOUT, ":utf8"; #FOR OUTGOING UTF8
binmode STDERR, ":utf8"; #AND FOR ERRORS SEPARATELY

use open qw/:std :utf8/;        #THIS ONE CAN BE PROBLEMATIC WITH DATA
+BASE INTERACTIONS
use open ':encoding(utf8)';     #ANOTHER WAY OF SAYING IT

use feature 'unicode_strings';  #ANOTHER PART OF 'TMTOWTDI' FOR PERL U
+NICODE

When it's someone else's code, however, the situation becomes more problematic. Be careful which modules you choose to incorporate.

Of course, if these options fail, and the UTF8 characters are not quintessential to your application, you can also remove them all and stick with a pure-ASCII solution. This may cause the least headache if UTF8 is not important to you. You could then use virtually any modules, and have no issue with any I/O operations. But it will not be very future-proof.

I look forward to the day when Perl has advanced to using unicode natively--by default. It's too bad that day is not already here.
