Hello, this is a devtools channel, so you’d have better chance moving this to a more general one, or better, filing a bug on bugzilla.mozilla.org (see https://web.dev/how-to-file-a-good-bug/) 
(FWIW I can see the rupee symbol in lastest Nightly on OSX)
It’s odd that the estimated results are 2,07,00,000 – is something modifying the page?
Thank you for your response
