Ruby Character to Unicode Converter

(and vice versa)

Forked from the original Gist script. I had to change the range from 109_967 in order to make it work.

Original description below.

I 'accidentally' created this while trying to make a string representation of the first million digits of the Champernowne constant. I thought it was pretty nifty, so I'm sharing.

Ever needed to find the Unicode value of some crazy-cool character like, say, ∀? Just

puts get_unicode('∀')

and you'll find its hex value is:

2200

Or if you've always been itching to know what Unicode character is represented by hex value 2752,

puts get_character('2752')

to find out. Go ahead — play with it — you know you want to!
