I created a simple script to map character codes in the 8bit range to Unicode for simple lookup:

https://github.com/tripleee/8bit

In the generated output, on Python 2.6.6 (but corroborated on Python 2.7.6), almost all character codes come up as "undefined" in CP874.

According to http://en.wikipedia.org/wiki/ISO/IEC_8859-11, CP874 should be a superset of ISO-8859-11, with a few character codes *added* in the ISO control range.

I'm not sure I understand the bug report. What's the problem ? :-)

The codec is a charmap codec generated from the file MAPPINGS/VENDORS/MICSFT/WINDOWS/CP874.TXT (http://ftp.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP874.TXT)

This mapping does have quite a few undefined characters.

BTW: The table on the wiki page shows the same undefined chars.
