I’m trying to implement the porter algorithm for French words.  
It’s seem that the current implementation in the gems ruby-stemmer and  
stemmer4r are flowed.  
For instance, trying to stem  
pétrolifère =\> petrolifer whereas I’m expecting petrol or pétrol

Has anyone encountered the issue and/or know a good working stemming gem  
for French words?

Thanks,

Vincent
