Every so often, I have to identify or research some Unicode characters. There’s a tool called uni 1 in the Perl 5 distribution App::Uni,2 developed by Audrey Tang and Ricardo Signes.
Let’s reimplement its basic functionality in a few lines of Perl 6 code and use that as an occasion to talk about Unicode support in Perl 6.
If you give it one character on the command line, it prints out a description of the following character:
$ uni њњ - U+0045a - CYRILLIC SMALL LETTER NJE
If you give it a longer string instead, it searches in the list of Unicode character names and prints out the same information ...
