None the less can you please give an actual case when case would

A trivial case is transcription from spoken or written material,

But these, as you say elsewhere, are "non text fields".
I don't think it would ever make sense for mail _transport_ to
work by converting headers to voice and back.
and I can think of at least one individual who habitually
transcribes domain names to all upper-case.
Then they deserve to have their references mangled ;-)
