cyrillic fonts problem

1.There is problem with cyrillic fonts in “Product data were exported from” if there type cyrillic it goes to be not readable.
2.and problem with price from site to pdf it goes to be like “Цена: 1,490.00 руб.” I think where is problem with new russian ruble sign “1,490.00 Р”
