use feature 'unicode_strings' tells perl to assume all strings are unicode.

use utf8 tell perl to assume all strings in the current source file are unicode.

Opening input files with a  :encoding layer will tell perl that the resulting strings are unicode.

 use encode contains subs that can be used to mark or convert strings from any other source as/to unicode.

Hope this helps
