Enter the command line interpreter and try to asign a string value that
contains the following: coding: 8bit. 

You get the error message that the encoding 8bit is unknown. This does
not happen in CPython.

This is it what you see on Jython:

Jython 2.5.1 (Release_2_5_1:6813, Sep 26 2009, 13:47:54)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_17
Type "help", "copyright", "credits" or license for more information.
>>> line = '"Content-Transfer-Encoding: 8bit"'
  File "<stdin>", line 1
SyntaxError: Unknown encoding: 8bit

Due to this bug the Wiki moin ( will not work with jython.

Wow, that's an unexpected bug, but it makes perfect sense. Looks like the problem is that we don't pass enough info down from the partial parse (in Py#compile_command_flags) to get the right sort of reader. So in particular, we should not be using ExpectedEncodingBufferedReader here.
