[Python-Dev] PEP: Adding data-type objects to Python

["Martin v. Löwis"]

As before, I'm doubtful what the actual needs are. For example, is
it desired to support generation of ID3v2 tags with such a data
format? The tag is specified here:

http://www.id3.org/id3v2.4.0-structure.txt

In ID3v1, text fields have a specified width, and are supposed
to be encoded in Latin-1, and padded with zero bytes.

In ID3v2, text fields start with an encoding declaration
(say, \x03 for UTF-8), then followed with a null-terminated
sequence of UTF-8 bytes.

Is it the intent of this PEP to support such data structures,
and allow the user to fill in a Unicode object, and then the
processing is automatic? (i.e. in ID3v1, the string gets
automatically Latin-1-encoded and zero-padded, in ID3v2, it
gets automatically UTF-8 encoded, and null-terminated)

If that is not to be supported, what are the use cases?
