IRIs instead of URIs

Recently
while working with Arabic legislation from Palestine, I found the odd
contradiction that though the document was entirely in Arabic, the
FRBR metadata URI refered to the documents using English terminology.
e.g.  /ps/judgement/1998-03-01 , which seemed odd because there was
no english being used anywhere else (in fact many of the users of
these documents may not be familiar with English at all) - right now
it isnt possible to use Arabic (or other non latin script languages
like Tamil or Chinese ) in Akoma Ntoso URIs - for e.g we cannot use
حكم
قضائي in
a Akoma Ntoso URI (which is the arabic translation of a judgement) 

As
suggested by Fabio earlier in response to my first email on this sometime back - it makes sense to support IRIs in Akoma
Ntoso URIs as there is a much larger character-set supported by it,
and it would support most non-latin writing systems.  The way to do
it currently in Akoma Ntoso is to use only  US-ASCII character set
and represent other writing systems by %-age encoding the letters -
which is not really human readable and defeats the purpose of having
readable URIs.  Also a point to note is that ICANN approved IDN
(internationalized domain names ) back in 2010.
