Sorting of strings is different in IronRuby than in Ruby

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 :slight_smile:
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.
