Hello! I was trying to import data from excel table via ajax, unfortunately i've stumbled upon this:
As you can see there is a lot of <?> symbols, they replace cyrillic characters. At the same time english text/numbers e.t.c displayed perfectly fine. As I dwelled in debugger I found that data itself gets corrupted at the stage of getting it with AJAX. So for example transfering something like "Водка водка 223" from .txt file will result in "????? ????? 223". There are same error symbols in debugger itself. Tested it with Chrome, on C2 and C3, same result everywhere. How can I deal with it?
