----------------------------------------
This bug is confirmed on 2.1.2p95
There are (at least) two valid euc-kr characters that do not get converted to utf-8 properly

**1. "\xA2\xE6" should convert to U+20AC (Euro Sign)**
Current behavior:

~~~ruby
irb(main):001:0> "\xA2\xE6".encode('UTF-8', 'EUC-KR')
Encoding::UndefinedConversionError: "\xA2\xE6" from EUC-KR to UTF-8
~~~

**2. "\xA2\xE7" should convert to U+00AE (Registered Sign)**
Current behavior:

~~~ruby
irb(main):002:0> "\xA2\xE7".encode('UTF-8', 'EUC-KR')
Encoding::UndefinedConversionError: "\xA2\xE7" from EUC-KR to UTF-8
~~~

I confirmed both characters convert correctly on python:

~~~python
>>> "\xA2\xE7".decode('euc-kr')
u'\xae'
~~~

I am guessing this is because these two characters are missing in this mapping:  http://svn.ruby-lang.org/repos/ruby/trunk/enc/trans/euckr-tbl.rb
