Subject: Re: How could I make the Ruby 1.9 string ignore the invalid utf-8 byte sequence in split?

I am working with Chinese character radicals.
I came across a radical which has a codepoint "\uE839".

-----

# encoding: utf-8
[ STDIN, STDOUT, STDERR ].each do |stdio|
  stdio.set_encoding( 'gbk', 'utf-8' )
end
char = "\uE839"
puts char # Encoding::UndefinedConversionError

-----
f.rb:7:in `write': U+E839 from UTF-8 to GBK
(Encoding::UndefinedConversionError)
  from f.rb:7:in `puts'
  from f.rb:7:in `puts'
  from f.rb:7:in `<main>'

But Perl works

-----
use utf8;
use open ":encoding(gbk)", ":std";

$char = "\N{U+E839}";
print $char;
-----
It prints out what I want--a chinese character radical
