Dear Unicode Experts,
In a discussion about a new protocol, there was some issue about how to 
replace illegal bytes in UTF-8 with U+FFFD. That let me remember that 
there was once a Public Review Issue about this, and that as a result, I 
added something to the Ruby (programming language) codebase. I traced 
this back to the method test_public_review_issue_121 added at 
http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/trunk/test/ruby/test_transcode.rb?r1=18291&r2=18290&pathrev=18291
and from there to http://www.unicode.org/review/pr-121.html.
What I now would like to know is what became of the UTC "tentative 
preference for option #2", and where this is documented, and if 
possible, which other programming languages and libraries use or don't 
use this preference.
On a higher level, this also suggests that it would be very good to add 
a bit more of (meta)data to these review issues, such as date opened and 
date closed and resolution.
After manipulating the URI a bit, I got to 
http://www.unicode.org/review/ and from there to 
http://www.unicode.org/review/resolved-pri-100.html, where I can find:
Resolution: Closed 2008-08-29. The UTC decided to adopt option 2 of the PRI.
This should be directly linked from 
http://www.unicode.org/review/pr-121.html (or just put that information 
on that page). Also, I'm still interested about where the result of this 
resolution is nailed down (a new version of the standard, with chapter 
and verse, or a TR or some such.
Regards,    Martin.
