Hindi characters not displaying?
First, let me say that I'm so excited to learn Hindi! Thank you to the contributors for your tireless efforts!
However, I just tried my first lesson and the cards didn't make any sense whatsoever. On my computer (macOS Sierra, 10.12.6) with Chrome (Version 67.0.3396.99), the characters were not rendering at all. All I could see when trying to distinguish between "i", "ī", "a" and "ā" were blank cards, some of which had a single dot in them. Even the errors I received looked more informative than that.
I reported the error on one of the cards (but not all of them b/c it took me a few tries to figure out something was wrong).
Happy to provide a screenshot if that's of any value.
Same problem for me, Chrome Version 67.0.3396.99 (Official Build) (64-bit)
Screenshots above. It appears that certain sizes of hindi characters are not rendering or are getting clipped by the browser. If you zoom in several times the character will render correctly.
