Gmail non-Latin address support to be followed by similar Google Calendar update
Google has added support for non-Latin and accented characters in email addresses on Gmail, in an effort to improve the company's overall multi-language support. The change, which will allow users to send and receive messages to and from addresses with characters not typically used in English, will apparently also spread to Google Calendar in the future.
The decision to alter how Gmail handles non-Latin characters stems from a new email standard created by the Internet Engineering Task Force (IETF) in 2012, according to an official blog post. The standard dictated that addresses could use such alphabets, but it would require every email provider to adopt it, with Google taking "the first step."
While the change is promising, Google has currently only enabled Gmail to recognize non-Latin email addresses. Google has yet to allow users to create Gmail accounts using non-Latin characters, but it hopes to do so in the future.
