Wrong encoding of the ads texts(ASCII,but must be UTF-8)

[Павел Х]

Hello!

AdMob ads are encoded with UTF-8 but for some reason when the're shown on the WP8 phone it looks like this:
"апропонуй ідею та виграй подарунок. Нам потрібен твій розум! Деталі тут."

there must be cirillic text in UTF-8.
And this problem is due to ASCII decoding for some reason if I'm right.

This affects all text ads from AdMob that we've seen to the moment.
