    CP273.TXT to be used with gencodec.py. Enables
    Communication with "old" IBM Mainframes

    Can you provide a reference of where and how this encoding
    is used ?

    We also need information of where the attached file originated.

    Thanks.

    The encoding is used on IBM Mainframes here in Germany
    and Austria. Mostly on "old" VM/VSE Machines. Rawdata is
    transferred via MQSeries and then encoded from "cp273" to
    "latin_1".

    The file has been translated from the original IBM RFC by
    myself.

    www.unicode.org has no equivalent file on their FTP-Servers
    (ftp://ftp.unicode.org/Public/MAPPINGS/).

    CP273 is an alias for this charset. source: IBM NLS RM Vol2
    SE09-8002-01, March 1990

    Given that the patch author has provided further details, can this patch be accepted now?

    @malemburg

    Member

    I guess so.

    Note that it's not a patch, but the template to be used with gencodec.py.

    Yes the patch can be included. The file should be used by gencodec.py

    Looks like it was never included. I guess '"old" IBM Mainframes' is a
    dwindling user base, should this one be closed?

    A Google search for "cp273 encoding" reveals that at least one other
    person needed it:

    "Old IBM Mainframes" are widely used in the financial industry. It
    would be good if the patch is included

    Like I said a few years: this can go in. Python is used a lot in the
    financial industry.

    The code page is referenced in this RFC:

    http://rfc.dotsrc.org/rfc/rfc1345.html

    This page has a good comparison of the various IBM code pages as shipped
    with different tools (jdk, glibc, aix, etc.):

    I tried figuring out to rebuild the codecs using the scripts in Tools/unicode/ but failed. Is the use of that directory documented anywhere?

    See the Makefile in that directory - that's what I use to build the
    codecs.

    If you just want to create a single codec, have a look at the
    gencodec.py module doc-string.

    The consensus is that this should have gone into Python years ago.

    In changeset d843a1caba78 (I screwed up the issue number in the commit), I added aliases according to http://lists.w3.org/Archives/Public/ietf-charsets/2002JulSep/0153.html plus what appears to be the conventional alias of just the number, and added it to the codecs docs, making a wild guess based on the issue title that the Language is German.
