Word Mac 2011 had essentially no support for Indic scripts, and we always recommended people use a different app for working in them. But the 2016 version (at least the latest update 15.30) seems much improved:
+The Tools/Language menu lets you mark text as Hindi, Gujarati, Kannada, Marathi, Tamil, Telugu, and Thai for spellcheck purposes.
+The standard MS fonts are provided for Devanagari, Gujarati, Kannada, Tamil, Telugu, Malayalam, Tibetan, and Thai.
+Apple fonts are recognized for Sinhala, Bangla, Oriya, Gurmukhi, Myanmar, Khmer, and Lao.
I don't know whether input and display of all these scripts, which often require reordering and complex ligatures, works correctly -- that will need a lot of testing.
Here is a Test Page with a PDF version of a .docx file containing a paragraph in each of the Indic scripts. I do not know them well enough to tell if there are position, ligature, or other errors. Readers who do know them are invited to comment on whether Word is displaying them correctly.
