Comment:

 Internationalization support was added in MacRuby 0.6. The previous
 version did not have a proper support for it.

 To see if something is really a bug you should first check with Ruby 1.9:
 {{{
 % ruby1.9 -e 'p "R\xFCbe"'
 "R\xFCbe"
 }}}

 \x is to specify bytes, not code points (that's what \u is for). In fact
 "R\xFCbe" would be "Rübe" in ISO-8859-1 (Latin-1), but MacRuby's default
 encoding is UTF-8 (like Ruby 1.9). And I would not recommend working in
 ISO-8859-1.

 {{{
 % macruby -e 'p "R\xFCbe".force_encoding("ISO-8859-1").encode("UTF-8")'
 "Rübe"
 }}}
 (note that String#encode was added this week-end in trunk so it will not
 work if you compiled your MacRuby before)

 In UTF-8, "ü" takes 2 bytes so if you want to write "Rübe" using \x you
 have to do: "R\xC3\xBCbe"
