A Google Groups thread confirms that Google Maps is lacking support for a common feature needed both here in the States and overseas, support for multi-language listings.

A Google Groups member asked:

Google’s official response is that there is no way to add more than one language URL for a single listing and that you should not add more than one business profile for the same physical address. Google Maps Jen said:

I am pretty sure many local search engines ask for languages spoken at the company when creating a business profile. I am not sure if those are one of the questions asked by Google Local. In any event, if multiple languages are spoken, adding a special URL for each language, should not be too hard.
