I don't think this is a bug.
According to RFC-2822 "From" can be "mailbox-list", which is a comma
separated list of "maibox". "mailbox" can be of "name-addr" which is
an optional "display-name" followed by "angle-addr". The interesting
part is "display-name":
display-name = phrase
phrase = 1*word
word = atom / quoted-string
"quoted-string" is quite clear: the quotes around text; we don't need
to view at it right here.
What's an "atom"?
atom = [CFWS] 1*atext [CFWS]
as CFWS is "comment" or "folding white space" we can ignore it right
now too.
atext = ALPHA / DIGIT / ; Any character except controls,
"!" / "#" / ; SP, and specials.
"$" / "%" / ; Used for atoms
"&" / "'" / "*" / "+" / "-" / "/" /
"=" / "?" / "^" / "_" / "`" / "{" /
"|" / "}" / "~"

No, it does not "imply". They're simply not necessary, as all used
character are part of what "atom" defines. Therefore it is a valid
"word". How it is *displayed*, i.e. if it is decoded and displayed in
it's "human readable" form is of no interest, or at least should not
be of any, for a MTA. So I'd say it is a bug in MTA software that does
not forward or store the message correctly.

Nothing astonishes men so much as common sense and plain dealing.
