A test which is OK on Firefox but not Inkscape

I can confirm this on Linux, stable version (0.48)

> I can confirm this on Linux, stable version (0.48)

I can't fully confirm this: based on local tests [1], the reported issue seems to depend on versions of external libraries, independent of Inkscape:
- reproduced with up-to-date stable versions of fontconfig/pango/freetype with Inkscape stable (0.48.5) and trunk (0.91pre2 r13534),
- not reproduced with same inkscape versions (stable 0.48.5, trunk r13534) but older versions of all dependencies

[1] all test done on OS X 10.7.5, with separate prefixes (MacPorts trees) for the dependent libraries.

Probably duplicate of Bug #168673 (sf1726379) "Support for ZWNJ".

~suv> the reported issue seems to depend on versions of external libraries

I have tested again with Farsi and Telugu texts, and the bug can be reproduced on Windows XP with 0.48.5, but is fixed with the trunk, revision 13740 (both versions use the same devlibs regarding fontconfig/pango/freetype).
The bug could also be dependent of both Inkscape and some dependencies...

[su_v (suv-lp)]

Cannot confirm as fixed in trunk on OS X 10.7.5: same results as already described in comment #5, stable Inkscape 0.48.5 as well as latest trunk build r13740 render with visible gap where none should be when using latest stable versions of dependencies. The font preview in 'Text & Font' though is correct.

The issue still exists in Inkscape 0.92.2 2405546, 2018-03-11 on Manjaro Linux 17.1.12
