As those quotes not part of the display name (at least I think so - e.g. they are also not shown by end user devices) I suggest to remove them from $pn and $fn, because otherwise you have to remove them manually with pv transformations/substr, which may takes much more performance...

jasmin,

the quotes are part of display-name:

display-name *(token LWS)/ quoted-string

and in some cases they need to be preserved.

perhaps a new textop or transformation (unquote) could be written to speed up removing the quotes.
