Can URL be in different languages?
And if your site is available in multiple languages, use the appropriate language in URLs for content in that language. So to sum it up, yes, non-English words and URLs are fine, [and] we recommend using them for non-English websites.
Should URLs be in local language?
It's fine to use localized words in the URL, or to use an Internationalized Domain Name (IDN). However, be sure to use UTF-8 encoding in the URL (in fact, we recommend using UTF-8 wherever possible) and remember to escape the URLs properly when linking to them.
