> Batik does not render unicode text of Indian languages correctly. I can demonstrate the problem with Rasterizer, but the problem may be present with other modules as well.
> Here is a simple svg file with Tamil text (attachment: test-tamil-rendering.svg) rendered to png by Batik and Inkscape for comparison.
> {noformat}
> java -jar batik-slideshow-1.11.jar test-tamil-rendering.svg{noformat}
> generated _test-tamil-rendering.png_. The text rendering here is faulty. [Compound form|https://en.wikipedia.org/wiki/Tamil_script#Compound_form] letters  are either detached (second letter மி), or wrong symbol attached and incompletely transformed (ழு, து). Positioning of dots above letters are off.
> For comparison, see _test-tamil-rendering.inkscape.png_ for correct rendering. This file was generated by inkscape.
> {noformat}
> inkscape --export-area-page --without-gui --export-png=test-tamil-rendering.inkscape.png test-tamil-rendering.svg{noformat}
> Also note that changing font (to Tamil specific font) did not improve/fix rendering.
