I know that the TAG has discussed issues around IRI equivalence, IRIs and HTML and so on before, and I can't claim to have explored every angle here, so I wondered if anyone else had any opinions on it and what we should do.

Two comments:

1) I think it's a known issue in HTML that when ISSUE-56 was "resolved", 
the text being re-added was something nobody likes, and which is known 
to be defective. It's certainly something that needs to be fixed.

2) "\" and "/":

2a) The uniform treatment of "\" hasn't agreement; for instance, Firefox 
does it only for file URIs (as far as I recall).

2b) That being said, "\" doesn't appear in syntactically valid URIs or 
IRIs anyway, so maybe we can ignore the question; it won't affect any 
valid URI/IRI anyway.

Best regards, Julian
