Subject: 25.1; Incorrect rendering for Bengali compound character
Date: Fri, 24 Feb 2017 03:45:46 +0530

The following Bengali compound character is not rendered correctly. To reproduce, start emacs -Q, and type / paste from a character map the following text:

ত্র (0x09A4, 0x09CD, Ox09B0) should be rendered as something that looks similar to এ. 

This sequence is rendered correctly in LibreOffice, gedit, and similar.

> Thank you so much for your super-quick solution! Yes, it works, and "tra" is rendered as it should be. The little bit of testing did not reveal any bad side effects. In particular, I tried many consonant + ra patterns and they are all correctly rendered. If I find any other problems after using this for some more time, I will report.

Thanks to both of you, I think we can therefore close this bug report.
