Much of this was intentional on my part.

For example, I intentionally avoided restrictions on what could be
stored as a tag in the database, (other than the terminating character
implied by "string" of course).

Yes, let's clarify documentation wherever we need to.

The headers should be decoded to utf-8, (via
g_mime_utils_header_decode_text), before being stored in the database.

No. The tag data is returned exactly as the user presented it.

I think a lot of the pain here is due to some bad design decisions in
python itself. Of course, my saying that doesn't make things any easier
for you.

But do tell me what more we can do to clarify behavior or documentation.
