Fortunately updmap is set up to embed all Type 1 fonts by default for
about two decades.

But doesn't the PDF specification explicitly allow not to embed fonts?
Adobe provided at least the LW35 fonts along with their products in
the past and offered font packages for other languages (CJK for
example) to be downloaded free of charge. 

Though IMO a document which has not all resources embedded cannot be
called "portable", it seems that Adobe violates the PDF specification

There are many documents out there which have not all fonts embedded.
Most annoying are documents produced by Adobe itself which look ugly
on Linux because fonts are substituted by "similar" fonts with
obviously different metrics.

IMO it was a big mistake to allow not to embed all fonts but it's also
a mistake to deliberately break documents which were created according
to this unfortunate specification.
