Kannada Unicode fonts used while taking the screenshots:

Note:

  • Opera Windows and Mozilla on Windows render them fine.
  • The default Mozilla package from mozilla.org (which uses xft) doesn't render Indic properly - only pango enabled build renders Indic fine. Most distributions now supply pango enabled build, which just need MOZ_ENABLE_PANGO env. variable set to 1 to run with Pango support.
