The Same author in different spelling

[Павел]

There is a Japanese author, who has both page for his name written in English Bow Ditama and Japanese ぢたま(某). Both pages have the books I read (Ｋｉｓｓ×ｓｉｓ（１） (KCデラックス), Kiss x Sis 1), practically these books are same. How this data should be handled? I don't want to have duplicate books on my shelves. Please help.

Add (not replace!) the roman name first on all editions. Go to the roman profile and combine.
