utf 8 - Get difference between two character codes in Ruby -

-

although might not readable, hoping can tell me if possible - , if how - make following code work

true if (string1 - string2) == predefined_distance

i hope might possible using ruby's open classes, looking @ documentation utf-8 , encoder::converter i'm not sure if it's possible do more <=> isn't @ precise. perhaps can convert ascii , compare values?

an example of use might compare 2 opening closing brackets, see if match instead of defining separate lists or containers each type of bracket, , instead can define distance 2 arbitrary characters.

built-in method ord of string class can return number of character:

true if (string1.chars.first.ord - string2.chars.first.ord) == predefined_distance
