The following font rendering rules for Malayalam (Indic language) are 
handled by operating system itself in the case of normal fonts.

  1.. Malayalam letter KA (0D15) + Malayalam Vowel sign E (0D46) has to be 
rendered as Malayalam Vowel sign E (0D46) + Malayalam letter KA (0D15)

  2.. Malayalam letter KA (0D15) + Malayalam Vowel sign O (0D4A) has to be 
rendered as Malayalam Vowel sign E (0D46) + Malayalam letter KA (0D15)+ 
Malayalam Vowel sign AA (0D46) etc..
But in the case of SVG document even if the glyph set are provided it is not 
rendering properly (i.e displayed in the order in which the text is 
provided).Is it because of lack of support of browser/OS/plugin? We can make 
the text render by changing the order in the text.But it is not the correct 
method as Chris Lilley point out.Can any one tell any  method for mentioning 
it in SVG Font file itself?

With regards
Jose Stephen
