SVG textpath unicode rendering issue screenshots and sample SVG

I am trying to render Unicode text (Telugu) on a curved SVG textPath. Text on textPath is not rendered properly on apple devices (Safari as well as Chrome), characters do not cluster as expected, where as text using rendered properly.

Where as same SVG code is workign as expected with Firefox and Chrome on Linux. Refer attached screenshots and SVG sample.

Testcase

@ahmad.saleem792 I think testcase_266832.svg contains first line as blank line. You may want to remove it to prevent "XML Parsing Error: XML or text declaration not at start of entity"

Yes - I marked it as 'obsolete' and added 'JSFiddle' in URL field. :-)
