    Thanks for the added details, Vinodh. It does look strange. I've passed this on to relevant people to look at.

    Both in Notepad & MS Word, Arial Unicode MS is the selected font. But you can see that, in MS Word only Devanagari is displayed properly, Tamil vowel signs are not placed properly. While in the Notepad, only Tamil display is correct

    See the below screenshot again:

    The same scenario is repeated with Kannada & Gujarati (both are supported by Arial Unicode MS)

    For some strange reasons, it seems in a Multi-Script text, only the first script block is rendered correctly.
