It works really well with any language that alternates vowels and consonants, which is most of them. I can also confirm it works great with Japanese, via Kotoe

It works really well with any language that alternates vowels and consonants, which is most of them. I can also confirm it works great with Japanese, via Kotoeri (kana input essentially alternates vowels and consonants, even more so than English). I have yet to run across a language where it isn't better than QWERTY, though I'm sure they exist. And less than 1 in 100,000 sounds awfully low. Where'd you get that number? There's 700,000 people living in my city and I personally know a lot more than 7 Dvorak users here. iOS does support Dvorak for Bluetooth keyboards, so it's not so niche to cause Apple to ignore it completely. Isn't "Dvorak on BT (only)" even more niche than "Dvorak"?
