After some thinking, my current opinion is. 1. Maybe NFC is better than NFKD, but I am not a Unicode expert.

2. I think the real bug is the order of escaping and normalization. The normalization (if a must) should be performed earlier right after valStr is created and only performed on valStr. Otherwise the NFKD normalization would generate new chars that need to be escaped. Again I am not a Unicode expert and I don't know if NFC will also do the same. If 2) is fixed, whatever is correct in 1) does not matter much. Thanks Max > On Sep 19, 2016, at 10:32 AM, Xuelei Fan <xuelei....@oracle.com> wrote: > >> 4.
