In the test text it is followed by two European numbers with a European separator between them. By rules W2, W3 and W6 of the Bidi algorithm (http://unicode.org/reports/tr9/#W2) the European numbers change to Arabic numbers, the ARABIC LETTER MARK changes to R and the separator changes to Other Neutral, and then by rule N1 the Arabic numbers make the separator change to R, so the final visual order is "a2+1؜", but the ؜ should not appear --> </head> <body> <p>a؜1+2</p> </body> </html>
