Description

Feature or enhancement

In many cases the name of the encoding matches the preferred MIME name, ignoring case and punctuation. But in some cases it is different (e.g. "ascii" vs "US-ASCII"). Python often accepts non-MIME names as well as MIME names, but other software can be more picky. Providing the preferred MIME name will allow to generate more standard documents (XML, emails, etc). We can add a public optional attribute mime_name to CodecInfo.

Research direction

Start by locating CodecInfo and the encoding-related tests in the CPython source, then inspect how encoding names are represented and resolved. The work is complete when the public optional mime_name attribute exposes the preferred MIME name, including cases such as ASCII versus US-ASCII, with tests covering the differing names.
