Do you have the HOME env set, or are you using the default location
(which is AppData/Roaming)? If you have HOME set to something else,
that's where .emacs needs to go.

If you used Emacs to navigate to ~/, then you've got the right place.

To double check, add an 'echo' statement, and check to see the message
at shell creation.

I get this message as well, but only at shell creation. So I have not
bothered to track it down.

Looks like (require 'setup-cygwin) was interfering with HOME and other
details and that's why things were getting borked.  Removed the above
package and it reads the .enacs_bash file correctly. 

Thanks, once again, for your help.  I set it to

I don't think `setup-cygwin.el' changes HOME.

AFAIK it does not change any env vars except SHELL and PATH.

It adds your Cygwin dir to PATH.  And it sets SHELL, `shell-file-name',
`explicit-shell-file-name', and `ediff-shell' to bash.exe in your Cygwin dir. 

Can you please try to figure out which part of `setup-cygwin.el' interferes with
your settings?  You can do this easily by commenting out different sections -
e.g. bifurcate until you find the offending bit.

Let me know and I'll try to make a reasonable fix to `setup-cygwin.el'.  Thx.

I probably should STFU instead of making wild assertions!  You're
right that there was nothing about HOME in it.  However, setup-cygwin
had something that was interfering with the shell invocation, which
again, would be my fault rather than anything of yours.  More below.

libotf is not used on Windows.  The native equivalent is Uniscribe,
which is installed by default on every version of Windows since XP.  If
you can view Arabic properly in other applications, then your system
should have a good enough version of uniscribe, but there are downloads
available on Microsoft's support pages if you have an old buggy version
(usually this is only a concern for Tibetan, Burmese and some Indic
languages, which were not supported by Windows until later).

This may be due to the font being used - try changing the font to a
specific Arabic font, rather than one for which Arabic happens to be one
of many languages covered. And make sure you are using a modern Truetype
font, not a bitmap font or older Truetype, as only fonts with OpenType
tables will have the neccesary logic built in to join characters.

Also, try searching the archives of emacs-devel on
mail.gnu.org. Something like this has been discussed before, and I know
a solution was found between Eli Zaretskii, the reporter and Kenichi
Handa, but it may have come too late to get into 24.1, and may need some
manual configuration to get working in the released version.
