The title of the first item (at top) does not exhibit Kashida in either IE or WebKit. Regarding the second item, it is not clear from the example attachment whether the content author manually inserted TATWEEL (U+0640) [= kashida] in order to produce the shown justification or if IE performed Kashida insertion. I suspect the former, which if true, would mean that WebKit was ignoring or mapping TATWEEL to the empty set when performing character to glyph mapping. It would have been useful if you had included the original HTML that produced this example.

Unfortunately I couldn't find that page on the net and I have not IE6 in order to test that what was behavior of IE6 but as in am seeing on IE10 on Windows8, text-align: justify; is not enough for doing kashida justification and text-justify: kashida; is also needed but I guess in IE6 quirk mode text-justify: kashida was enabled by default (that is not important for us I guess). Here is my test http://fa.wikipedia.org/w/index.php?oldid=8341664#Justification that you can see on IE in doing text-justify I want to propose changing this bug as a CSS3 feature ( http://www.w3.org/TR/css3-text/#text-justify ) request on text-justify: kashida; but I don't think this is a blocker for Bug 76173 as it was not on Firefox counterpart bug ( https://bugzilla.mozilla.org/show_bug.cgi?id=536557 ).

Kashida justification is removed from CSS3 (http://www.w3.org/TR/css3-text/) and deferred to CSS4 (http://dev.w3.org/csswg/css-text-4/). See also: * http://stackoverflow.com/a/20790740 * http://www.microsoft.com/middleeast/msdn/JustifyingText-CSS.aspx
