FYI

Please note that information given by 'Shantanoo' above here, is about entire Devnagari script for multiple languages and not limited to the language in discussion that is Marathi. Hence out of the scope of this bug which has been place after consensus at Marathi language wikipedia . Scope given to Shantanoo is for three alphabates अ‍ॅ र्‍य र्‍ह and not beyond

Thanks and Warm Regards

This can be fixed locally by modifying following link.

http://mr.wikipedia.org/wiki/Mediawiki:Edittools

From the page history
http://mr.wikipedia.org/w/index.php?title=Mediawiki:Edittools&action=history

Mahitgar (mr.wikipedia.org/wiki/User:Mahitgar) from mr.wikipedia.org can modify the page.

This bug may be closed, unless no one can modify the http://mr.wikipedia.org/wiki/Mediawiki:Edittools link.

EditTools and WikiEditor are separate things.

The WikiEditor bar above the editing box should have all the Devanagari characters that can be useful to anybody. I'm surprised that WikiEditor has many Indic scripts, but not Devanagari. It should be added in the file
WikiEditor/modules/jquery.wikiEditor.toolbar.config.js

EditTools appears under the editing box. It can be customized locally, as Shantanoo says.

Changing title to avoid confusion.

The characters were added. This change will be deployed to all the projects soon.

If any changes will be needed, please open a new bug.

(And thanks to Shantanoo!)
