IDN now supported by Google AdWords
If you write your ads in any language other than English, you may have wished that you could make your display URL consistent with the rest of your ad by showing your internationalized domain name. Today, we’re announcing that we now support non-ASCII characters, including non-Latin characters and Latin characters with accents and diacritics, in display and destination URLs.
When you create an ad in AdWords, you can now enter Unicode characters in the display and destination URL fields. To ensure that users will be able to reach your site, we’ll verify that the URL works properly in both Unicode and Punycode.
We also want to make sure that users are not shown URLs in any language other than their own, so we’ll render the display URL in Unicode characters only if its language matches the user’s Google interface language. In all other cases, it’ll be shown in Punycode.
Remember that all of our AdWords policies regarding display and destination URLs still apply. In particular, the domain of the display and destination URLs must match, so if you use non-ASCII characters in the display URL, make sure to do the same in the destination URL.
