I wrote "Targaarii Dovaogeedii jemis" as an answer since I don't have an easy way to include macrons, but Duolingo marked my answer as wrong.
I know this is an old comment, but it now works as intended.
I'm sorry to disappoint, but I just encountered the issue mentioned above, so it doesn't seem to work.
Same here :/
Targārī has no sound (for me at least)
