The code for extending ::first-letter through punctuation to the first non-punctuation character doesn't cross changes in directionality. The underlying problem here is (currently, anyway) likely the same as bug 509685. However, I'd like a separate bug for this particular case because it affects a rather large number of tests in the CSS 2.1 test suite. That said, I'm not sure the spec shouldn't change here. I tend to think that if the :first-letter would include any characters with directionality different from the block's directionality, we probably shouldn't create the ::first-letter style at all. Currently, the spec only has an exception for the case: # Similarly, if the first letter(s) of the block are not at the start of the # line (for example due to bidirectional reordering), then the UA need not # create the pseudo-element(s). This causes the following tests to fail due to the tests for extension through the given characters: http://test.csswg.org/suites/css2.1/20101001/html4/first-letter-punct-before-002.htm http://test.csswg.org/suites/css2.1/20101001/xhtml1/first-letter-punct-before-002.xht 05C0;HEBREW PUNCTUATION PASEQ;Po;0;R;;;;;N;HEBREW POINT PASEQ;;;; 05C3;HEBREW PUNCTUATION SOF PASUQ;Po;0;R;;;;;N;;;;; 05C6;HEBREW PUNCTUATION NUN HAFUKHA;Po;0;R;;;;;N;;;;; 05F3;HEBREW PUNCTUATION GERESH;Po;0;R;;;;;N;;;;; 05F4;HEBREW PUNCTUATION GERSHAYIM;Po;0;R;;;;;N;;;;; 060D;ARABIC DATE SEPARATOR;Po;0;AL;;;;;N;;;;; 061B;ARABIC SEMICOLON;Po;0;AL;;;;;N;;;;; 061E;ARABIC TRIPLE DOT PUNCTUATION MARK;Po;0;AL;;;;;N;;;;; 061F;ARABIC QUESTION MARK;Po;0;AL;;;;;N;;;;; 066B;ARABIC DECIMAL SEPARATOR;Po;0;AN;;;;;N;;;;; 066C;ARABIC THOUSANDS SEPARATOR;Po;0;AN;;;;;N;;;;; 066D;ARABIC FIVE POINTED STAR;Po;0;AL;;;;;N;;;;; 06D4;ARABIC FULL STOP;Po;0;AL;;;;;N;ARABIC PERIOD;;;; 0700;SYRIAC END OF PARAGRAPH;Po;0;AL;;;;;N;;;;; 0701;SYRIAC SUPRALINEAR FULL STOP;Po;0;AL;;;;;N;;;;; 0702;SYRIAC SUBLINEAR FULL STOP;Po;0;AL;;;;;N;;;;; 0703;SYRIAC SUPRALINEAR COLON;Po;0;AL;;;;;N;;;;; 0704;SYRIAC SUBLINEAR COLON;Po;0;AL;;;;;N;;;;; 0705;SYRIAC HORIZONTAL COLON;Po;0;AL;;;;;N;;;;; 0706;SYRIAC COLON SKEWED LEFT;Po;0;AL;;;;;N;;;;; 0707;SYRIAC COLON SKEWED RIGHT;Po;0;AL;;;;;N;;;;; 0708;SYRIAC SUPRALINEAR COLON SKEWED LEFT;Po;0;AL;;;;;N;;;;; 0709;SYRIAC SUBLINEAR COLON SKEWED RIGHT;Po;0;AL;;;;;N;;;;; 070A;SYRIAC CONTRACTION;Po;0;AL;;;;;N;;;;; 070B;SYRIAC HARKLEAN OBELUS;Po;0;AL;;;;;N;;;;; 070C;SYRIAC HARKLEAN METOBELUS;Po;0;AL;;;;;N;;;;; 070D;SYRIAC HARKLEAN ASTERISCUS;Po;0;AL;;;;;N;;;;; http://test.csswg.org/suites/css2.1/20101001/html4/first-letter-punct-before-003.htm http://test.csswg.org/suites/css2.1/20101001/xhtml1/first-letter-punct-before-003.xht 0830;SAMARITAN PUNCTUATION NEQUDAA;Po;0;R;;;;;N;;;;; 0831;SAMARITAN PUNCTUATION AFSAAQ;Po;0;R;;;;;N;;;;; 0832;SAMARITAN PUNCTUATION ANGED;Po;0;R;;;;;N;;;;; 0833;SAMARITAN PUNCTUATION BAU;Po;0;R;;;;;N;;;;; 0834;SAMARITAN PUNCTUATION ATMAAU;Po;0;R;;;;;N;;;;; 0835;SAMARITAN PUNCTUATION SHIYYAALAA;Po;0;R;;;;;N;;;;; 0836;SAMARITAN ABBREVIATION MARK;Po;0;R;;;;;N;;;;; 0837;SAMARITAN PUNCTUATION MELODIC QITSA;Po;0;R;;;;;N;;;;; 0838;SAMARITAN PUNCTUATION ZIQAA;Po;0;R;;;;;N;;;;; 0839;SAMARITAN PUNCTUATION QITSA;Po;0;R;;;;;N;;;;; 083A;SAMARITAN PUNCTUATION ZAEF;Po;0;R;;;;;N;;;;; 083B;SAMARITAN PUNCTUATION TURU;Po;0;R;;;;;N;;;;; 083C;SAMARITAN PUNCTUATION ARKAANU;Po;0;R;;;;;N;;;;; 083D;SAMARITAN PUNCTUATION SOF MASHFAAT;Po;0;R;;;;;N;;;;; 083E;SAMARITAN PUNCTUATION ANNAAU;Po;0;R;;;;;N;;;;; (these all appear to be new in Unicode 6) http://test.csswg.org/suites/css2.1/20101001/html4/first-letter-punct-before-025.htm http://test.csswg.org/suites/css2.1/20101001/xhtml1/first-letter-punct-before-025.xht 10857;IMPERIAL ARAMAIC SECTION SIGN;Po;0;R;;;;;N;;;;; 1093F;LYDIAN TRIANGULAR MARK;Po;0;R;;;;;N;;;;; 10A50;KHAROSHTHI PUNCTUATION DOT;Po;0;R;;;;;N;;;;; 10A51;KHAROSHTHI PUNCTUATION SMALL CIRCLE;Po;0;R;;;;;N;;;;; 10A52;KHAROSHTHI PUNCTUATION CIRCLE;Po;0;R;;;;;N;;;;; 10A53;KHAROSHTHI PUNCTUATION CRESCENT BAR;Po;0;R;;;;;N;;;;; 10A54;KHAROSHTHI PUNCTUATION MANGALAM;Po;0;R;;;;;N;;;;; 10A55;KHAROSHTHI PUNCTUATION LOTUS;Po;0;R;;;;;N;;;;; 10A56;KHAROSHTHI PUNCTUATION DANDA;Po;0;R;;;;;N;;;;; 10A57;KHAROSHTHI PUNCTUATION DOUBLE DANDA;Po;0;R;;;;;N;;;;; 10A58;KHAROSHTHI PUNCTUATION LINES;Po;0;R;;;;;N;;;;; 10A7F;OLD SOUTH ARABIAN NUMERIC INDICATOR;Po;0;R;;;;;N;;;;;
