This is almost identical to: http://bugs.python.org/issue854511
However, tis602, which is mentioned in the orginal bug report, is not an alias to cp874. Therefore, I propose the following:

import encodings

aliases = encodings.aliases.aliases
more_aliases = {'ibm874'     : 'cp874',
                'iso_8859_11': 'cp874',
                'iso8859_11' : 'cp874',
                'windows_874': 'cp874',
               }
aliases.update(more_aliases)

Please provide evidence that those encodings are indeed the same.

Thanks.

Something is wrong with your request, though:

* we already have an iso8859_11 code, so aliasing it to some
  other name is not possible

* we already have an cp874 code, so aliasing it to some
  other name is not possible

* cp874 differs from iso8859_11 in a few places, so aliasing
  cp874 is not possible (see http://en.wikipedia.org/wiki/ISO/IEC_8859-11#Code_page_874)

What we could do is add aliases 'x-ibm874' and 'windows_874' to
'cp874'. I'm not sure whether 'ibm874' and 'x-ibm874' are the same
thing. The references only mention 'x-ibm874'.

Sorry about that.

The following document says the following are aliases: x-IBM874, cp874, ibm874, ibm-874, 874
http://www.java2s.com/Tutorial/Java/0180__File/DisplaysAvailableCharsetsandaliases.htm
http://www.fileformat.info/info/charset/x-IBM874/index.htm
In addition it seems that 'windows_874' is used (that's the one that raised this issue for me), but I've also seen references of windows-874, windows874 , WIN874:
http://doxygen.postgresql.org/encnames_8c_source.html

The following document says the following are aliases: x-IBM874, cp874, ibm874, ibm-874, 874
http://www.java2s.com/Tutorial/Java/0180__File/DisplaysAvailableCharsetsandaliases.htm

http://doxygen.postgresql.org/encnames_8c_source.html

From what I can tell

cp874 != ibm_874 != iso_8859_11

What I can say is that the current cp874 is the implementation of the windows_874 code page. The page itself references the microsoft code page, and also contains the appropriate characters (like EURO SIGN).

https://github.com/python/cpython/blob/master/Lib/encodings/cp874.py
""" Python Character Mapping Codec cp874 generated from 'MAPPINGS/VENDORS/MICSFT/WINDOWS/CP874.TXT' with gencodec.py.

https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP874.TXT

It seems appropriate to at least alias windows_874 with cp874. They are provably the same.

If someone needs the IBM standard, they may have to write a different code page.

I've created the codepage alias 874.

This is only pending is a merge into the mainline.

Thanks.

This is an easy alias to a valid codepage. I supplied proof that they are the same.

I don't understand why this has been allowed to languish for 9 months.

Did I miss something? Is there more work I need to do?

Thanks

Bumping this again.

I'd like to try and understand why this change can not or has not been approved.

I added the technical info here to the github PR.

Is there a shortage of reviewers? What can I do to help speed up the process?
