Hi

For those of us not so well versed in I18N issues, what do you mean by normalization? 

Is it just consolidating look-alike code points, like the multiple hyphens that exist in Unicode? 
Does it also involve removing Arabic and Hebrew points? (I think Paul raised this one) 
Does it involve removing diacritics?
Does it involve splitting combined characters (like U+00E6 into 'a' and 'e')?
Is there a standard we can point to and say "do this before comparing or hashing"?

Thanks

Yoav
