[EP-tech] Re: Normalize characters for correct sorting
I probably didn't make myself clear what the real problem is. In English
you don't have the same vowel with and without accent. It is only matter of
correct spelling. So it is the same letter and has to be normalized to be
sorted correctly. If you see Tokenizer.pm
(/perl_lib/EPrints/Index/Tokenizer.pm) does the same for indexing.
