From my testing, the combinations TSA+AA and DZA+AA are definitely rendered
incorrectly in Noto.
Also, it seems that the DZA should act like JA when joining with U and UU, but
it doesn't.
Attaching screenshots of TSA+AA, DZA+AA, DZA+U, and DZA+UU, comparing them to
equivalent CA and JA sequences.

The report of challa.anilkumar@gmail.com shows dotted circles when these
consonants are followed by vowels. That is what I was seeing in the software
available to test the fonts during the design process. That means that at the
time these characters were too new to be supported.
I no longer get dotted circles in Windows 8.1 at least.
We would have to decide whether to invest in an upgrade of the existing
versions, or if this can wait until the one that is the plans.

Jelle, I don't know what software the submitter of the document is using.
That's irrelevant to us.
These characters are defined in Unicode 5.1, published in March 2008. (They
have also been supported in HarfBuzz for years.) We definitely consider this
bug part of the existing phase.

While I can understand that this may be considered a technical bug against the
specification for the existing phase, I just want to record the fact that
neither of these characters is actually used anywhere outside of the works of
the 19th Century Telugu linguist and writer C.P. Brown, who invented them to
record sound distinctions not normally captured in Telugu script.

@nizarsq : Nizar could you prepare a test case with the above text and assign it back to me? Thanks

Sure. I'll update the bug when the test case ready. Thanks
Test case created.
I am getting e-mail messages about this. A test case for this issue looks like this:
First and third line compare with original without modifier on the second and fourth lines. This is the Serif. The Sans has the same glyph set and the same rendering rules. The picture is from Mac Pages. The text is: ౘా ౘి ౘీ ౘు ౘూ ౘృ ౘౄ ౘె ౘే ౘై ౘొ ౘో ౘౌ ౘ్ ౘ్ద ౘ్ౘ ద్ౘ ౘ్ర చా చి చీ చు చూ చృ చౄ చె చే చై చొ చో చౌ చ్ చ్ద ౙా ౙి ౙీ ౙు ౙూ ౙృ ౙౄ ౙె ౙే ౙై ౙొ ౙో ౙౌ ౙ్ ౙ్ద ౙ్ౙ ద్ౙ ౙ్ర జా జి జీ జు జూ జృ జౄ జె జే జై జొ జో జౌ జ్ జ్ద ౚా ౚి ౚీ ౚు ౚూ ౚృ ౚౄ ౚె ౚే ౚై ౚొ ౚో ౚౌ ౚ్ర ౚ్ద ఴా ఴి ఴీ ఴు ఴూ ఴృ ఴౄ ఴె ఴే ఴై ఴొ ఴో ఴౌ ఴ్ ఴ్ద This issue can be closed!
