bug#21260: 23.2; Devanagari windows 10

[Jim Funderburk]

Hi, Eli -
  Here is another dropbox link with further info you requested:
https://www.dropbox.com/s/3er09sc7jc8m5kc/emacs-devanagari.zip?dl=0
  There are two images:
  1. emacs-devanagari.png    This is a screen shot of me opening up the 
file
     in Emacs via  command line,  and of what the file looks like on my 
system.
     It looks like all boxes.
  2. emacs-Ctl-h-H.png     This is screen shot of what emacs shows 
after Ctl-h-H command.
       As you can see, the South Asian language shows up in boxes, 
also  'Hindi' and 'Kannada'
       Also  (maybe outside of the image)  Tamil and Telugu - all South 
Asian languages.
  You asked what font -  when I do menu Options/Set Default Font, it 
shows as Courier New.
      I have tried changing to Arial, Lucida Sans Unicode, Consolas  
with no improvement.
   Note:  I thought maybe  this is due to a deficiency in the fonts in 
Windows 10.  However,
               When I open the file in Notepad,   the Devanagari 
displays just fine;  Notepad
                shows that it is using Consolas Font.
   Note2:  Also, I have a Windows Vista system and this displays fine 
in the same Emacs 23 on that system.
   Note3:  ALso, I tried Emacs 24 on Windows 10, and the same problem 
occurs.

   So, As of now, it seems like there is a bug in displaying South 
Asian Unicode text in Emacs on Windows 10.

THanks for looking at it.   Let me know if I can do anything more to 
help the issue to get resolved.

Regards,
 Jim Funderburk
