Subject: [ruby-core:23158] Inconsistent behaviour of String#strip

The following behaviour of String#strip seems inconsistent to me:

irb(main):003:0> a = "\xa0".force_encoding("ISO-8859-1")
=> "���"
irb(main):004:0> a.strip
=> ""
irb(main):005:0> a = "a\xa0".force_encoding("ISO-8859-1")
=> "a���"
irb(main):006:0> a.strip
=> "a���"

This is with ruby 1.9.2dev (2009-04-07 trunk 23150) [i686-linux]

I'm submitting here rather than redmine since I don't really understand what
is the intended behaviour of String any more - so it could be my faulty
understanding rather than an implementation bug.
