These modules should help you. If these don't scratch your itch, try searching CPAN for 'Unicode'.

Unicode::CharName
Converts between the character code and the Unicode character name, and gives you the class the character belongs to.
Unicode::String
Try the $us->utf8( [$newval] ) function. To quote the description from the page:
The UTF-8 encoding use 8-bit for the encoding of characters in the range 0x0 .. 0x7F, 16-bit for the encoding of characters in the range 0x80 .. 0x7FF, 24-bit for the encoding of characters in the range 0x800 .. 0xFFFF and 32-bit for characters in the range 0x01000 .. 0x10FFFF. Americans like this encoding, because plain US-ASCII characters are still US-ASCII. Another benefit is that the character '\0' only occurs as the encoding of 0x0, thus the normal NUL-terminated strings (popular in the C programming language) can still be used.
Unicode::Map8
Quote the CPAN:
The Unicode::Map8 class implement efficient mapping tables between 8-bit character sets and 16 bit character sets like Unicode. The tables are efficient both in terms of space allocated and translation speed. The 16-bit strings is assumed to use network byte order.

BTW, I've never used these. I just searched CPAN.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":


  • Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —

  • You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
            For:     Use:
    & &amp;
    < &lt;
