7 years ago Apple Pages has the same issue. (Coretex)
Google Chrome has this the same issue. (Harfbuzz)
MS Word 2016 (mac version) doesn't have this issue. (Don't know what they use)
In the image. Top window is MS word 2016, Bottom window is Pages.

7 years ago @MayuraVerma Just to make sure, you used the same font (Noto Sans Kannada) in both MS Word 2016(mac) and Apple Page/Chrome in your screenshot, didn't you?
@TidharC can you test sample sequences in this bug given with the latest harfbuzz (from github)? If it still has this issue, a bug has to be filed against HarfBuzz.

7 years ago @jungshik In the above example, I had used "Noto Serif Kannada", but this is the same case with "Noto Sans Kannada"
Re-phrasing the issue: Both Noto Sans Kannada and Noto Serif Kannada has problem rendering "ರ್ಕ ರ್ಖ ರ್ಗ ರ್ಘ ರ್ಙ ರ್ಚ ರ್ಛ ರ್ಜ ರ್ಝ ರ್ಞ ರ್ಟ ರ್ಠ ರ್ಡ ರ್ಢ ರ್ಣ ರ್ತ ರ್ಥ ರ್ದ ರ್ಧ ರ್ನ ರ್ಪ ರ್ಫ ರ್ಬ ರ್ಭ ರ್ಮ ರ್ಯ ರ್ರ ರ್ಱ ರ್ಲ ರ್ವ ರ್ಶ ರ್ಷ ರ್ಸ ರ್ಹ ರ್ಳ ರ್ೞ", Text Reference: https://en.wikipedia.org/wiki/Kannada_alphabet
Failed with Noto Sans/Serif Kannada:
Passed with Noto Sans/Serif Kannada:
Failed
If somebody can please file the bugreport to Apple as well. I can do it as user. Apple ignores it. If somebody from this team can file and get traction on the Core Text team. It will be great.

7 years ago @MayuraVerma can you test on Windows 7 with IE 11? BTW, Chrome on Windows uses HarfBuzz.
BTW, if you have Windows 10, testing on WIndows 10 with Edge would be nice, too. When testing on Windows, it'd be nice to use Noto {Sans, Serif} Kannada. After installing the fonts, you can either make a simple html page to explicitly set the font or use DOM inspector to change fonts in an existing page (e.g. Wikipedia).

7 years ago I put up a test page at http://jungshik.github.io/noto/kannada/bug763.html (it uses Web fonts so that nothing need to be downloaded).

7 years ago @jungshik this is with windows 7 and IE 11
It seem to have any issue displaying text.
I will check with windows 10 and edge in the evening.

7 years ago Thanks, @roozbehp, for the reference to a harfbuzz bug. It looks like there's not much do on the font side. Is there?
@MayuraVerma Thanks for the screenshot. So, IE 11 on Win 7 behaves like MS Word (, which is not always the case). Anyway, this had better be dealt with in behdad/harfbuzz#341 .

7 years ago @jungshik Now the wiki page https://en.wikipedia.org/wiki/Kannada_alphabet#Consonant_Conjuncts looks fine after swapping "U+0ccdU+200d" to "U+200dU+0ccd"
Wiki Page was encoded incorrectly. But I wondered how the reverse sequence also worked for MS Word!

2 years ago Thank you. This is not a font issue. Thanks for closing issue.
I am not sure if this is Noto Sans Kannada defect in Chrome on Mac or if this is Chrome issue or harfbuzz issue.
There seems to be an issue with "ZERO WIDTH JOINER" and "\u0cb0\u0ccd" combination. \u0cb0\u0ccd\u200d\u0c95
incorrect display in chrome
correct display in ms word
Check the below text in chrome and comparing it with Microsoft word.
