Bug #1839: String#tr borked for UTF-8 0080..00FF

=begin

a = "uber"
=> "uber"
a.encoding
=> #Encoding:UTF-8
b = a.tr("u","ü")
=> "\xFCber"
b.encoding
=> #Encoding:UTF-8

What's more remarkable,

b.valid_encoding?
=> true

!!!

b << "x"
=> "\xFCberx"
b.valid_encoding?
=> true

!!!

And yet it works for codepoints > 255:

c = a.tr("u","ł")
=> "łber"
c.encoding
=> #Encoding:UTF-8

=end

Oops, I pasted ruby -v instead of ruby19 -v. The correct version is:
