Subject: Bug in Ruby Regexp?

Hi,

Whilst trying to fix the iso-8859-1 support in Rexml, I came across
this:

ser@valentine ~/Work/rexml $ ruby -e '
puts /\A([^<]*)/u.match("Koln</test>")[0]'
Koln
ser@valentine ~/Work/rexml $ ruby -e '
puts /\A([^<]*)/u.match("K�ln</test>")[0]'
K�ln</test>
ser@valentine ~/Work/rexml $ ruby -e '
puts /([^\<]*)/.match("K�ln</test>")[0]'
K�ln

(sorry about the line formatting; Google wraps lines)

'�' is a valid ASCII character; it's even got an ASCII value of less
than 256. The mapping for this character is the same value for unicode
as it is for iso-8859-1;  Is this a bug in the unicode support in
Regexp?
