persistent-id decode errors

It's not, it's how all multi-valued attributes are handled.

It's not controllable, which keeps the escaping process required sane.

The data is URL encoded like any HTTP header is, and semicolons are
included in that encoding. They rarely if ever appear in actual data,
which is why it was chosen.

Yes, in the abstract. Some attributes are single-valued in definition, but
there is nothing preventing multiple values from showing up. Many/most
attributes tend to be multi-valued definitionally anyway, whatever people
like to think.
