devanagari font in Acrobat, bug

Brief: Acrobat treats devanagari texts as a Western script and loses all ligatures.

Check it yourselves: go to http://www.sacred-texts.com/hin/mbs/mbs03282.htm

copy any devanagari text there, paste it in Microsoft Word, then copy it from there and paste it in Acrobat ("Create PDF from Cipboard"), apparently all is OK, but it is a wrong impression, and in fact it is a mixture of image and text. To check it, copy the created text in PDF and paste it back in Microsoft Word, and you will see the reality.

So with the first line of the above-mentionned site:

एतस्मिन्न एव काले तु दयुमत्सेनॊ महावने

Acrobat will output:

एत       एव काले तु दयुम  ेनॊ महावने

Microsoft Office has corrected that bug, not yet Adobe, though it has Adobe Devanagari font, where it is used as a Western script.
