Is this fixed in the 2.3-dev branch yet? I really don't want to use an extension for such a core feature. I feel like it'll not be safe in the long run. Honestly, UTF-8 support should have been implemented years ago. OpenCart supports unicode URLs and crushes on SEO in this regard.

@thunderapps,

Product should be saved and accessible via the front-end with a pretty URL name similar to the product title. eg. /物品.html

Such expectation is wrong, the feature never existed in Magento 1 either and needs to be thoroughly evaluated prior to such system behavior change. As far as I remember, Magento is only able to convert product name into latin letters for some languages currently.

GitHub is intended for bug reports, please use https://github.com/magento/community-features for other suggestions like improvements or feature requests.

I just accidentally bumped into magento/magento2-jp#77, where they seem to work on adding support for this (for Japanese at least).

[orlangur]

Great finding, @hostep! Surprised by transliterator in Japanese-specific module, I believe there were some in core for Greek or Cyrillic letters.
