Earlier today, someone posted a topic with some hiragana and kanji in the topic title:
Try copying the URL of that topic and pasting it into a new tab. The page doesn’t load for me on Chrome, Safari, or Firefox on macOS. I suspect that this is because there is kanji and hiragana in the permalink. I put some kanji and hiragana in the title of this topic to test this theory.
I’m guessing Ember doesn’t handle routes with non-ascii characters correctly. Links to the topic work, however, because Ember handles transitions within an app that’s already loaded differently.
