keyboard viewer, devanagari, missing characters
I'm learning to type in Hindi using the inbuilt Devanagari - QWERTY keyboard but I'm getting only a partial display of characters on one of my iMacs.

ie:
Can anyone explain why this is happening and is there a way for me to fix it?
I have already tried deleting the .plist in keyboard prefs but it didn't help.
Thanks
iMac 27″, macOS 10.13
