Subject: Re: do your bit for my mental health - how to find the difference between two strings?

Thanks for all the responses, though I was looking for the difference between two seemingly identical string, I will keep the levenshtein distance algorithm around for another future project :)

this bore some info. I'm running Ruby 1.92 (sorry, I should have mentioned that) with Sinatra 1.1.0. With the replace function the encoding is US-ASCII, or UTF-8 if I set the `# encoding: utf-8` at the top of the file.

Without the replace function the encoding is ASCII-8BIT. I've been searching around for how to make all this work now I know this, and poking around in the Sinatra and Rack source, but haven't found a (working) answer yet. I'll post it when I do.

Thanks very much for the help.

Iain
