Hi

On pressing  hve  in devanagari-itrans input method the following should be
rendered - ह्वे
But Emacs-25.3 (built from source) does not render this correctly. It
splits the ` mark and places at the end of line.
Similar behavior is observed on pressing d which should render द् but it
does not.
I have attached an image to show the problem. This however works fine on
Emacs 24 (installed via package manager - apt)

Here is my system info -

OS: Ubuntu 16.04.3 LTS
Kernel: 4.4.0-104-generic

Here are the config options with which I built emacs 25.3

./configure --with-all --with-xaw3d  --with-xwidgets --with-x-toolkit=gtk3
--with-png --with-m17n-flt --with-xft

​Thanks
,
Aviral

I cannot reproduce this.  I'm not on Ubuntu, so this probably means
your m17n libraries are either outdated, or they have a bug.

Maybe Emacs 24 was built against different versions of the libraries
that participate in shaping complex scripts?

Dear Eli,

You are right. The m17n libraries are outdated. I updated them and
recompiled Emacs 25.3 but the problem persisted.
Due to time constraints, I am not looking forward to debugging this issue
further.
I will continue working with  Emacs 24.5.1 for now.
Hopefully when I upgrade to Ubuntu 18.04, I will get new m17n libraries
with Emacs 25.x and this issue won't show up.

​Thanks
,
Aviral
