But it does behave in firefox with a few modifications. Here is the part that is problematic, because of right-to-left unicode: </p> <p> ordinary, then <font face="SBL Hebrew">אִישׁ</font>.<a href="#sd"><sup>24</sup></a>, then ordinary. </p> <p>Now consider the same text with a slight modification: </p> <p> ordinary, then <font face="SBL Hebrew">אִישׁ</font>.a<a href="#sd"><sup>24</sup></a>, then ordinary. </p> <p> Weird, isn't it? Notice that in the first case, in firefox the writing continues to be right-to-left even after the close of the unicode font. In the second case, the order is restored to left-to-right immediately (which is the correct behavior). In Konqueror, the behavior is incorrect in both instances. </p> <p>It makes no difference when I put the unicode in decimal form: </p> <p> ordinary, then <font face="SBL Hebrew">אִישׁ</font>.<a href="#sd"><sup>24</sup></a>, then ordinary. </p> <p> ordinary, then <font face="SBL Hebrew">אִישׁ</font>.a<a href="#sd"><sup>24</sup></a>, then ordinary. </p> <p>The problem disappears when I remove the hyperlink: </p> <p>ordinary, then <font face="SBL Hebrew">אִישׁ</font>., then ordinary. </p> </BODY> </HTML> Reproducible: Always Steps to Reproduce: 1. Just take the html file in "details" and open it in firefox. (I'll be happy to resupply it if it is corrupted by this transmission.) Actual Results: The characters are not all displayed in the proper left-to-right positions. Expected Results: Right-to-left display should be turned off immediately upon exiting a right-to-left unicode font.

This is INVALID - the current behaviour is correct. According to the Unicode Bidirectional Layout algorithm (http://www.unicode.org/reports/tr9/), a run of characters with weak types (such as digits) should be laid out in the same direction of the strong-type characters (e.g. letters) which it follows. The neutral characters in between (a period, in your example) are then also laid out in the same direction. So the entire "Hebrew Letters + period + digits" sequence is laid out right-to-left. The closing or opening of inline elements (such as <font>, in this case) does not (and should not) have an effect on this. You can work around this in your case by placing a LRM control character where you placed the "a" in your "working" example. <p> ordinary, then <font face="SBL Hebrew">אִישׁ</font>‎.<a href="#sd"><sup>24</sup></a>, then ordinary. </p>
