Hoi,
At translatewiki.net we installed the latest release of the Lohit fonts today. Among several improvements there are two things that stand out. There are now two new fonts specific for Devanagari and they support Marathi and Nepali. As you know certain characters are written differently when used for these languages. 

The Lohit Devanagari font does allow for the use of a local override but this requires a browser who deals with this properly and a source where the meta data explicitly states that the language is either Marathi or Nepali. By providing a font that is hard wired to show the variations for Marathi or Nepali a solution is provided that will always work.

Our plan is to test the new Lohit fonts on translatewiki.net this week and have them go into production on Monday on all the WMF wikis with WebFonts support.

Please test the Lohit fonts in your script and let us know as soon as possible when there are any issues.
Thanks,
    Gerard
