Question about MUC and xmpp4r (encoding issue)

[Björn Herzig]

Ok, i could pinpoint the problem.

It's basically an encoding problem. Whenever i receive german umlaut an exception gets
thrown and i get disconnected from the server

W, [2010-01-02T01:37:17.139421 #2071] WARN -- : EXCEPTION:
REXML::ParseException
#<Encoding::CompatibilityError: incompatible encoding regexp match (UTF-8 regexp with ASCII-8BIT string)>

I'm not a ruby expert. How can i work around this?

Björn,

Here's what I ended up doing:

msg.gsub!(/\x01/,'*')
msg.gsub!(/[\x02-\x1F]|[\x7F-\xFF]/,'')

Not a good long-term solution, but it works for me for now...

That's a Ruby 1.9 issue (since Ruby 1.9 now supports different file- and
data-encodings). Ruby seems to be unsure about the encoding of the
String you want to match, but knows that it's not 8bit-clean and thus
interprets it simply as binary (a.k.a. ASCII-8BIT). You'll have to
force the String you want to match to be interpreted as UTF-8. This
could be achieved by

str = str.force_encode('utf-8')

HTH.
