Japanese characters are missing on report

Hi, 

I have created some quizzes in Japanese and published to my account. Then I looked up the quiz result from HISTORY option. The report with Japanese characters appeared perfectly on the display as below.

In order to print out the report I clicked the PRINT button on the right hand side corner. Then  I see the incomplete report with all Japanese characters disappeared. (please see below)  

Is there a way to fix this problem?

Addition to this issue, all characters are garbled on CSV file when I use  EXPORT option.
