Converting text character to javascript

Hi guys!

i’m looking for a certain plugin that allows me to change text into javascript

You see, I own this guide to learn Japanese blog where I have included Japanese text. Whenever there are post with Japanese text, my adsense will start showing Japanese advertisements. I don’t want the Japanese adsense ads to appear. So my solution is to change the Japanese text into javascript.

Are there any plugins that allows me to easily convert the Japanese text to javascript?

thanks!
