DM Smith commented on LUCENE-2102:
----------------------------------

bq. but non-NFC text doesn't work correctly throughout most of lucene's analysis components as it is now anyway, so I don't think we should worry about it right now. Maybe we could add a comment for the future though.

It might be good to note the NFC (NFKC?) requirement in the JavaDoc.

Maybe its just me, but I think it is critical to normalize the input to Lucene for both indexing and searching. Unless a NFCNormalizingFilter is added to Lucene, I think it is the responsibility of the caller.
