Hey Andreas,

Lately, there have been some discussions on ruby-core (the mailing list
dedicated to the core implementers of MRI). It's possible that this bug is
being adressed at the moment. These are the most recent messages there:

I don't really know what could be causing this difference. :(

Hi,<br>
<br>
the following code behaves strangely in ruby 2.0, and different from<br>
1.9:<br>
<br>
puts &quot;=E4&quot;.match(/[\p{Word}]/).inspect<br>
puts &quot;=E4&quot;.match(/[\p{Word}\s]/).inspect<br>
<br>
Result on 1.9.3-p194:<br>
#&lt;MatchData &quot;=E4&quot;&gt;<br>
#&lt;MatchData &quot;=E4&quot;&gt;<br>
<br>
Result on 2.0.0-p0:<br>
#&lt;MatchData &quot;=E4&quot;&gt;<br>
nil<br>
<br>
Any ideas what&#39;s going on there?<br>
<br>
I have attached the ruby code as a file, in case there are any problems<br>
with email charset conversion.<br>
<br>
Thanks!<br>
Andreas<br>
