Fonts:

• Noto Sans Devanagari
• Noto Serif Devanagari

Bug:

• Incorrect rendering of the following:
  र + ॢ = रॢ
  र + ॣ = रॣ

Source: fonts.google.com

Few Devanagari fonts render it the correct way, & I am sharing screenshots.

• Red : Noto Sans Devanagari

• Green : Mukta, another Devanagari font, that renders correctly. That is how Noto Sans Devanagari is expected to render.

Kindly consider fixing this.

Furthermore, do consider adding support for all the Devanagari characters supported by the latest version of Unicode.
