287342 - Mozilla renders Tamil characters in the wrong order - specifically it swaps positions of vowel symbols and consonant symbols

Status: RESOLVED EXPIRED

(Core :: Internationalization, defect)

Description

[Amit Singh]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.6) Gecko/20050225 Firefox/1.0.1

When viewing Tamil language (a South Indian language) sentences on Wikipedia,
Firefox incorrectly renders the order of some letters - specifically it swaps
the positions of vowel and consonant sounds. Internet Explorer renders it
correctly. Also, as soon as the word that is misspelled is copied and pasted in,
say, wordpad or an MSN messenger conversation window, the correct order of
symbols is restored.

Reproducible: Always

Steps to Reproduce:
----Part 1----
- Go to http://en.wikipedia.org/wiki/Tamil_language#Grammar 
- Read first word in Tamil script 
- Try opening same page in Internet Explorer, the order of the symbols will be
different.
---- Part 2----
- I tried copying and pasting the relevant HTML codes from the Webpage into a
HTML file. 


Actual Results:  
---Part 1---
- Mozilla renders the order of symbols wrong

---Part 2----
- Opening this "test" HTML file results in the same error.

Expected Results:  
செல்லாதிருப்பவர்  - > this is how Mozilla renders it ( I have copied from the same
web page)

ெசல்லாதிருப்பவர்  - > this is how it should be rendered

Attachment: copied HTML out of Wikipedia page - I used it to compare rendering between IE and Firefox

View on IE and Firefox - even if you can't read the language (which is probably
the case) you should be able to tell the difference in symbol order.

It works for me using the above build. While I'm not familiar with Tamil, I am
somewhat familiar with Hindi, so the type of script is not too foreign. I went
to the Wikipedia page, and compared that one word and also the sample passage
below it, and it looked the same to me in IE and Firefox. Again, I'm no expert
on Tamil, but nothing seemed out of place.

Amit, can you try again using a recent Firefox nightly build instead of 1.0.1?
Perhaps that will fix the issue. If you can let us know if it works for you in
that, it would be helpful. You can get a nightly build here:

http://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/latest-trunk/

(Note that nightly builds may be unstable and/or contain bugs that aren't
present in 1.0.1. If this is a problem, don't try :) )

Did you enable Tamil (or any complex script) support on Windows XP? MS IE just
works without that, but Mozilla relies on that.

This is an automated message, with ID "auto-resolve01".

This bug has had no comments for a long time. Statistically, we have found that
bug reports that have not been confirmed by a second user after three months are
highly unlikely to be the source of a fix to the code.

While your input is very important to us, our resources are limited and so we
are asking for your help in focussing our efforts. If you can still reproduce
this problem in the latest version of the product (see below for how to obtain a
copy) or, for feature requests, if it's not present in the latest version and
you still believe we should implement it, please visit the URL of this bug
(given at the top of this mail) and add a comment to that effect, giving more
reproduction information if you have it.

If it is not a problem any longer, you need take no action. If this bug is not
changed in any way in the next two weeks, it will be automatically resolved.
