Re: ap_unescape_url can't escape %uXXXX

[IKEBE Tomohiro]

I have written a little patch for libapreq which unescape
the %u style URI-escaped string.
the unescape algorithm is based on CGI.pm

 Is this a known issue?

Hi IKEBE,

Any idea if/when that'll be incorporated to the distributions?

I currently have to have a handler check every incoming request
for failure, and then convert with Unicode::String

You may want to take this issue up on [EMAIL PROTECTED]
Personally I've never seen this kind of character encoding, 
and my reading of

  Section 8 at http://www.w3.org/TR/charmod/ 
  and RFC 2718, Section 2.2.5, 

seems to indicate that this isn't a recommended practice. OTOH, IIRC the 
apache source claims to support utf8 extension(s) of www-urlencoded
ASCII, so if people really are using such encodings, supporting 
%u in ap_unescape_url shouldn't hurt server performance at all.

In any case, putting together a patch of ap_unescape_url along the lines 
of CGI::Util's utf8_chr() can't hurt :-).

my WinIE 5.5 / WinIE 6.0 uses this style of URI escaping when you use
javascript to submit page's content. (Well, I'm talking about
MovableType's bookmarklet, if you're interested)
