This seems something worthy of adding to the codecs doc as a footnote. Perhaps something like "(deprecated) ... gb2312 is an obsolete encoding from the 1980s. Use gbk or gb18030 instead." will do.
> libiconv-1.14 is also using the wrong version.
Just a side note on the right/wrongfulness of libiconv: I have reported the GB18030 incompatibility as a libiconv bug.[1] From the replies, I learnt that 1) what libiconv is using currently is a then-official mapping published on ftp.unicode.org; 2) vendor implementations of gb2312 differed historically. I have updated the corresponding section[2] on Wikipedia to include these old references.

[2]: https://en.wikipedia.org/wiki/GB_2312#Two_implementations_of_GB2312
Still, being old and common does not necessarily mean being correct, as Ma Lin have demonstrated by showing the character semantics. To reflect this in a better-supported manner, I have added names for the glyphs in question from GB2312-80 to [2].
