because i'm using daily nokogiri i wanted to test loofah with a small
script (coming from http://loofah.rubyforge.org/loofah/) :

#! /opt/local/bin/ruby1.9
# encoding: utf-8

require 'rubygems'
require 'nokogiri'
require 'loofah'

unsafe_html="ohai! <div>div is safe</div> <script>but script is
not</script>"

doc=Loofah.fragment(unsafe_html).scrub!(:strip)
puts doc.to_s

however i got :

SyntaxError:
/opt/local/lib/ruby1.9/gems/1.9.1/gems/loofah-1.0.0/lib/loofah/html5/scr
ub.rb:20: too short escaped multibyte character:

ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-darwin10]
over Mac OS X SL

I am unable to reproduce this issue on 1.9.2p0, current 1.9.2 trunk, 1.8.7p249 or any other of several (current) ruby versions.

I need more details on your system in order to diagnose this issue. What else can you tell me?

[unbewusst]

I'm using : loofah (1.0.0) with nokogiri (1.4.3.1) under Mac OS X SL 10.6.4 (latest)
libxml / libxsl have been installed thru MacPorts :
libxml2 @2.7.7_0 (active)
libxslt @1.1.26_0 (active)

also i got exactly the same error with the following :
puts Loofah.xml_document('org.ytho.launchctl.list.plist').is_a?(Nokogiri::XML::Document)

notice that 'org.ytho.launchctl.list.plist' is a valid xml.

i'll be happy to answer any question, thanks !

I'm seeing this error consistently on a couple of machines with 1.9.2:

  ruby 1.9.2p0 (2010-08-18 revision 29036) [x86_64-linux]
  ruby 1.9.2p0 (2010-08-18 revision 29036) [i386-darwin9.8.0]

However, the expression does not raise an error on init with:

  ruby 1.8.6 (2009-06-08 patchlevel 369) [universal-darwin9.0]
  ruby 1.8.7 (2010-08-16 patchlevel 302) [i686-darwin9.8.0]

Might be a 1.9.2p0 bug, but I'm not sure yet.

I get the same error. More details
ruby 1.9.2 (p180)

and commad used to run ruby is

ruby -KU -E utf-8:utf-8 -rubygems

[flavorjones]

I have a fix for this issue. Will be released early next week. Sorry for the delay.

[flavorjones]

Fix is in 1.1.0, just released.

@flavorjones
This issue is appeared again on ruby 2.0 (I'm using ruby 2.0.0p195)

[flavorjones]

Please open a new issue. Thanks.

[tbbooher]

is there a new issue on this one?

[svenfuchs]

seeing this issue on ruby 2.0, too

maybe it'd make sense to add a matrix to .travis.yml and test against various ruby versions? :)

[zhon]

Having same problem on ruby 2.0. What is the new issue number?

Hi, I also get same error, but in my case, it is probably not loofah's fault. Because it happens when I add 'gem feedzirra' and 'bundle install'.
https://rubygems.org/gems/feedzirra
Unfortunately the published version without specifying the version is old and doesn't have gemspec yet (while the master branch already has gemspec). So bundler installs loofah 1.0.0 for the gem, which had not supported ruby1.9, in my environment.

When I specify feedzirra 0.2.0.rc2 so that the error disappears.
I use ruby 2.0.0p247

@ntaoo Thanks for the info. Removing feedzirra from my Gemfile eliminated the error.
