bug#25864: 25.1; Incorrect rendering for Bengali compound character

[handa]

Hi,

Which Bengali font are you using with Emacs?
If you are not sure about it, please type C-u C-x = while putting point
(cursor) on that incorrectly rendered Bengali character.  The *Help*
buffer shows which font is used.
