[mp2] OutputFilter with UTF-8 characters

Matthew Darwin Wed, 05 Nov 2003 15:47:13 -0800

I'm just wondering if anyone has any input on this issue. I'm implementing an output filter, like so:

<Files *.pcgi>
SetHandler perl-script
PerlResponseHandler ModPerl::Registry
PerlOutputFilterHandler Apache::Kinnetics::Output
</Files>

and I get the following error on some web pages that have UTF-8 data:

[Wed Nov 05 17:30:00 2003] [error] [client 127.0.0.1] panic: sv_pos_b2u: bad byte offset at /kinnetics/component/perllib/site_perl/Apache/Kinnetics/Output.pm line 221.

Line 221 is the start of this regex:

s{ <\?nm(              # opening angle bracket
   (?:          # Non-backreffing grouping paren
   [^>'"] *       # 0 or more things that are neither > nor ' nor "
   |      #    or else
   ".*?"    # a section between double quotes (stingy match)
   |      #    or else
   '.*?'    # a section between single quotes (stingy match)
   ) +          # repetire ad libitum
         #  hm.... are null tags <> legal? XXX
   )\?>          # closing angle bracket
}{kinnetics_handler($r, $1)}geisx;  # mutate
