It occurs because Adobe Arabic is a CFF font but does not use a 1000-unit emsquare to define the glyph outlines, it uses 2048 units. When it is embedded in the PDF, the (correct) /FontMatrix entry gets ignored and the result is that the glyphs are scaled incorrectly.</div><div><br class="webkit-block-placeholder"></div><div>I believe this is really a bug in the PDF viewers involved. It happens with both Apple's PDFkit and Adobe Reader 8. I have reported it to both, but it might help if other people complain as well!</div><div><br class="webkit-block-placeholder"></div><div>Note that if you view the same PDF files with an earlier version of Adobe Reader (e.g., Acrobat Reader 5 or Adobe Reader 7), or with a viewer such as Evince on Linux, the glyphs look fine; these programs interpret the embedded font correctly and respect its /FontMatrix entry.</div><div><br class="webkit-block-placeholder"></div><div>JK</div><div><br class="webkit-block-placeholder"></div></body></html>
