"Unicode provides a unique number for every character, no matter what the platform, no matter what the program, no matter what the language."

Unicode is a code table that assigns integer numbers to characters. There are alternatives to represent the integer values as a sequence of bytes. One is the UTF-8 encoding which is a convenient way to use Unicode in Unix-style operating systems.

unum is a stand-alone Perl utility which allows you to look up Unicode and HTML characters by name or number, and interconvert numbers in decimal, hexadecimal, and octal bases. It is installed on Abel in /usr/local/bin/unum
unum 57005
unum 0x2622
