Today I decided to reinstall my Windows 8.1 and haven't done any Opera's files copying. Instead I relied on Opera bookmarks synchronization. So after all things done I installed Opera, logged in and found that some folders in my bookmarks were missing! I tried to follow this link https://sync.opera.com/web/ but there were none of the missing one! The only thing I suspect in disappearing is that particularly these folders' names were written in japanese charcters. Would such a turn to be a problem in a time of global accesebility? I've been using japanese language in Opera all the time so it would be natural to create folders in japanese, right? These were the most important for me. I hope this problem may be solved somehow otherwise why there a japanese languaged Opera at all if somebody can not create folders in the interface language and be sure one's bookmarks would be safe.
My current version of Opera is 33.0.1990.115
