Sorry about that, I did a bug when trying various ways to override BiDi behavior of my PUAs, and I just saw that my test documents where encoding the RLO after the PUAs (I had to hexdump my test file to see what was happening). Encoding it before the PUAs effectively works in IE and NotePad on Windows (but the <bdo dir="rtl"> method does not work, as it just modifies the paragraph alignment style and does not force the BiDi behavior of characters that are not Bidi-neutral). My opinion is that bd=L was a bad choice for PUAs that should have better used a bd=ON property, like for standard generic punctuation marks which are already neutral in general. I really don't understand the rationale for a _strong_ LTR directionality for PUAs, and why we can't even use a RLM to override only one PUA within a otherwise RTL text; having to use RLO implies lots of caveats when editing a text document where there are also portions with Latin letters, as it completely disables the normal automatic Bidi rendering.
