Hi William, Thanks for reaching out to us.
Kindly see below responses to your queries: - a list of which languages the Ads API officially supports (does it match the Google Translation API, or are there differences?) >> Kindly note that Google Ads API officially supports only the English >> language. However, for targeting criteria, you may find this document. - a list of any extra invalid characters for KeywordPlans in foreign languages. The ones I'm aware of and already strip out are (as a PHP array): [':', ',', '!', '@', '%', '^', '(', ')', '=', '{', '}', ';', '~', '`', '<', '>', '?', "\", '|','.'] >> Extra invalid characters for KeywordPlans are related to a specific client >> library. I recommend you to reach out to the respective client library owner >> by filing an issue on the issue tracker on the Issue tab of your chosen >> client library on github, so that they can provide guidance on it. Also does Google do any post-processing on keywords? >> You may reach out to the Product Team via this link for further guidance >> since their team is more equipped to handle product related queries.
