Hm, I don't see how it can. For example, in my case the collation 
strength is set as

CollationAttribute(EVColAttribute.kStrength) = EVColAttributeValue.kSecondary

This ignores case, but not accents, and works fine for SQL searches.

But for RegEx, case *is* considered unless I add (?i) to the search. 
So RegEx ignores the collation strength attribute, at least in this 
instance.
