Chinese, Korean, Japanese font issue

I am using the Google Font "Roboto Condensed" on a website that must display in the Chinese, Japanese and Korean languages also.

Here is an example of what the font looks like:

@import url('http://ift.tt/1Rac5P6');

html {
    font-family: 'Roboto Condensed', sans-serif;
    font-size: 18px;
 }

From my tests, the font renders differently in JP, KO and ZH depending on which browser I view it in.

Is there a solution for this? Is this an appropriate font for those three languages?

Thank you so much for your help! Maurice.
