I think this issue can be reopened In many printed books which I hav come across, ttra is written in as a ligature with the following form (https://archive.org/details/bengaligrammar00wenggoog/page/n24/mode/1up)
পুত্ত্র পৌত্ত্র ( book link ) glyph in some other fonts of fonts.google.com
I'm not sure we need to reopen - what's wrong with the fix?
I mean in the printed books which I have seen, including Vidyasagar's Varnaparicaya which is one of the basis for Modern Bengali typesetting. The glyph of ttra ত্ত্র is different from what is proposed here. Glyph which is proposed here by the issue raiser
Oh, huh, so it needs re-drawing. Understood.

Issue
Noto Sans Bengali does not display the TTRA character as a ligature. The character form in NotoSerifBengali and prior version of NotoSansBengali had the character displaying correctly. According to our records the version 2.000 (2017/9/20) had the character form as the following: https://github.com/googlefonts/noto-fonts/blob/bc9353da6f625b7a47035de952c2e8fd9e3ae889/hinted/NotoSansBengali-Regular.ttf
However, in Version 1.03 (2015/9/26), the font displays the character as a ligature as the following: https://github.com/googlefonts/noto-fonts/blob/ad153f5a14c838afb16c83f0a02784c7605f1e21/hinted/NotoSansBengali-Regular.ttf
On the other hand, the Noto Serif fonts display the ligature correctly.
