Cyrillic symbols convert to ? when importing csv to data tables

I created csv file:
Name SpeakerId Text ResponseText Branches Traits Conditions PreAction PostAction AudioClip
Episode0_Start blank Русский Текст #Basic:Episode0_1
Episode0_1 blank #Basic:Episode0_2

Output after importing it to data tables I got:
Name SpeakerId Text ResponseText Branches Traits Conditions PreAction PostAction AudioClip
Episode0_Start blank ??? ??? #Basic:Episode0_1
Episode0_1 blank #Basic:Episode0_2

So I need manually change the data in tables (like I did in second string) and this is not good.

Structure:

Hi ,

Does this occur in a clean, blank project with no additional content or is it limited to one project? Do you have a sample .csv file that shows this behavior I can try on my end?

Looks like the problem is in Microsoft Excel. I imported this csv file to google docs and then exported it again - works fine.
There is a first file before importing it to google: http://mlpxz.com/DT_DemoDialogue.csv

Hi ,

I was able to reproduce this on my end and have entered a bug report, UE-19896, to be assessed by the development staff.
