Hi,
Steps to reproduce:
Open a file containing UTF-8 Devanagari script in Emacs. It is rendered
incorrectly. For example, in the word "लिखने", The first and second
rendered characters are swapped. Konsole (Qt) renders this correctly.
A page on the EmacsWiki suggests a workaround that works on Ubuntu
though [1].
Thanks.

Emacs 23 and later shifted the support of Indic (and any
other complex scripts) to OpenType fonts. And, on
GNU/Linux, you need libotf, m17n-db, and m17n-lib to make
Emacs render those scripts correctly by OTF.

It's not a "workaround" but the right thing on GNU/Linux
systems.

Thanks for the explanation.

I see. Well, I suppose I should put it like this then:
1. Emacs should then refuse to render Devanagari without the required
libraries, not render them incorrectly.
2. I have those libraries installed on my Debian Sid machine, and
Emacs still doesn't render them correctly. I don't suppose this
belongs here- I'll head over to bugs.debian.org.
Thanks.

emacs-snapshot is deliberately built without m17n/otf support, so
this is not a bug.

Ah, I see. By the way, why is it built without m17n/otf support?

Historically because when m17n/otf support was added to Emacs, the
m17n/otf packages in Debian were outdated and the maintainer was
apparently missing. But now that I look into it again, it seems that
they have a new maintainer and the state of the packages looks
pretty good, so I think I'll enable m17n/otf in a future snapshot
release.

What do you exactly mean by "refuse to render Devanagari"?
Show just empty boxes for each character?

Yeah, or something like that. Isn't that better than rendering
something that's incorrect and misleading?

I'm not sure. I myself prefer seeing each character by its
original shape (i.e. no-reordering, no-ligature,
no-positioning) than seeing just empty boxes.
It may be good to highlight incorrectly rendered part by
some warning face.

Sure, that makes sense.
