Yes.
phonetic-given-name and phonetic-family-name is very important to in
Japanese.
The kanji has plural pronunciation, and the meanings are different, too.
Therefore, a sort using given-name and family-name is difficult.
I think that I can solve this problem by adding phonetic-given-name and
phonetic-family-name.
I think it to be feasible by adding an own properties to ContactsAPI[1].
Users of many Japanese will also wants this correspondence.

Thank you for your time.
