Hi

I was playing around with a very simple code example and got different  
results in IronRuby and in Ruby.

“IronRuby In Action”.split(//).sort.uniq.join

returns in MRI: " AIRbcinortuy"  
returns in IronRuby: " AbciInorRtuy"

I’m sure you guys are aware of this, but just in case 🙂  
I guess in the end the 2 results should be the same or is this perhaps  
something that has to do with encoding?

Cheers  
Ivan

We end up calling String.CompareTo which performs a lexicographical  
comparison. This is the source of the different behavior. This should  
be filed as a bug in RubyForge if it hasn’t been already.
