Hello!!! Today, I would like to tell about how Google services, namely Google AdWords, work with non-Latin URLs. 

Google has solved the problem of incompatibility of Google AdWords advertising service with IDN-domains that contain non-Latin characters.

Previously, creating a new ad, one had to use punycode-equivalent of International domain names. For example, игры.рф, had to be entered as xn--c1ajz8b.xn--p1ai. And now Google changed it.

In July 2011, Google Adwords began to support Internationalized Domain Names for display and destination URLs on Google ads. This means advertisers will no longer have to show a non-ASCII ad followed by an ASCII domain name.The new list of acceptable characters also includes accents and diacritical marks.

AdWords clients can enter unicode characters for the URLs and Google will verify that it works correctly in both unicode and punycode.

The display URL will only show up only in cases where the language matches that of the user’s Google interface, otherwise it will render in punycode.
