<div class="">I decided to write a brief blog article about arabic email addresses and here it is <a href="http://schappo.blogspot.co.uk/2016/03/arabic-email-addresses.html" class="">http://schappo.blogspot.co.uk/2016/03/arabic-email-addresses.html</a></div>

<div class="">Without bidi isolates or any other form of intervention the email address مارك@رسيل.السعودية wholly displays L⬅︎R<br class="">
<br class="">
I have just created a temporary page to show how the arabic address مارك@رسيل.السعودية appears in L➡︎R Context & L⬅︎R Context using bidi isolates.
<a href="https://co-project.lboro.ac.uk/users/coas/arabic-email.html" class="">https://co-project.lboro.ac.uk/users/coas/arabic-email.html</a><br class="">
<br class="">
With reference to my page :<br class="">
<br class="">
The L➡︎R Context gives an email address in a structure more familiar to a L➡︎R reader. The structure being, in this case,
<a href="mailto:local-part@label.label" class="">local-part@label.label</a>. It does not matter which direction a label text is. Each label could have a different direction and again it would not matter. A L➡︎R reader would readily recognise this as an email
address. Personally I find it much easier to recognise an email address when written like this.<br class="">
<br class="">
Similarly for the L⬅︎R Context<br class="">
<br class="">
I have used html to illustrate. In a word processing document one would use the Unicode isolates U+2066➡︎2069. It would be the responsibility of the software to automatically implement/insert/apply the bidi isolation for display of the email address to users.<br class="">
<br class="">
There are indeed other cases but I think the same principles outlined above can be applied.<br class="">

<br class="">
That's already the requirement for processing, according to IDNA2008<br class="">
(that is, IDNA is label by label, not over the domain name). So so<br class="">
far, I agree.<br class="">
<br class="">
I don't have an intuition as to what would be clear to a user; perhaps<br class="">
you have one.<br class="">
<br class="">
But …<br class="">

<blockquote type="cite" class="">Lets take a 2 level domain name: 2ndLevelD.TLD where each label is written in a Right to Left Script.<br class="">
<br class="">

<br class="">
… I'm slightly worried about this, because I suspect you're also going<br class="">
to need something that is unsurprising where the different labels are<br class="">
in different directions. <br class="">
<br class="">
<blockquote type="cite" class="">I believe that using bidi isolates leads to easier to comprehend domain names/email addresses for both Left to Right readers and Right to Left readers.<br class="">
<br class="">

<br class="">
This is also probably true, but since an awful lot of cases don't<br class="">
include the markup to indicate the bidi isolates, there's still that<br class="">
problem too. This includes (just for instance) email, particularly<br class="">
the headers. So while the mark up helps I'm wondering what to do<br class="">
about other cases.<br class="">
