The test passes my environment:

• ruby 1.9.3p194 (2012-04-20 revision 35410) [x86_64-darwin11.4.0]
• ruby 1.9.3p203 (2012-05-04 revision 35536) [x86_64-freebsd9.0]
• ruby 1.9.3p243 (2012-06-28 revision 36244) [x86_64-freebsd9.0]
• ruby 2.0.0dev (2012-07-02 trunk 36265) [x86_64-freebsd9.0]

Anyone can reproduce it?

No feedback, closing.

2012/7/2 "Martin J. Dürst" [e-mail]:

\ue863 is in the Unicode private use area. Therefore, conversion to GBK
should not succeed. I get Encoding::UndefinedConversionError just for
ruby -e '"\ue863".encode("gbk")'

I don't understand why the title of the bug is "when convert ... from GBK to
UTF-8". The last method call of the test, .encode('utf-8'), is quite
irrelevant. Justin, can you explain what you want?

I guess Justen expected round-trip.

Because GBK is narrow, now I use GB18030 to avoid this error. :-)

#!/usr/bin/env ruby -w

encoding: utf-8

require 'test/unit'

class Tests < Test::Unit::TestCase
def test_gbk
"\ue863".encode('gb18030').encode('utf-8')
end
end
