Apologies, Till, for the delayed reply - I *thought* replying on a bug
also subscribed me to it, but clearly not! (I have subscribed now).

There is a bit of guess work here, as I don't fully understand the file
locations.

We are mainly concerned with the cidfmap file. Now, there is a set of
cidfmap files in "/etc/ghostscript/cidfmap.d/" and those (it appears)
are used by the "/usr/sbin/update-gsfontmap" script (poor name, as it
adds to the confusion that Fonts and CIDFonts are the same thing!), to
update the *actual* cidfmap which is in
"/var/lib/ghostscript/fonts/cidfmap". It is not at all clear to me how
the "update-gsfontmap" script gets run - possibly only as a package
post-install step?

The files in "/etc/ghostscript/cidfmap.d/" are as follows (file name +
TTF font(s) referenced):

90gs-cjk-resource-cns1.conf - ukai.ttc, uming.ttc
90gs-cjk-resource-gb1.conf - ukai.ttc, uming.ttc
90gs-cjk-resource-japan1.conf - fonts-japanese-mincho.ttf, fonts-japanese-gothic.ttf
90gs-cjk-resource-japan2.conf - ttf-japanese-mincho.ttf, ttf-japanese-gothic.ttf
90gs-cjk-resource-korea1.conf - NanumMyeongjo.ttf, NanumBarunGothic.ttf, NanumBarunGothicBold.ttf, NanumGothic.ttf

NOTE: there is some inconsistency (possibly bitrot) there with "fonts-
japanese-*.ttf" used in one file and "ttf-japanese-*.ttf" used in
another - clearly the same font, but likely different "generations" of
name.


My two alternate solutions are that the Ghostscript package should be augmented to include the fonts listed above (with the names and paths updated to reflect the current directory tree etc) as dependencies, thus they always get installed with Ghostscript.

*Or* to split off (I *think*) the files in "/etc/ghostscript/cidfmap.d/"
into something like a "ghostscript-cjk-cidfonts" package, which has
those fonts listed above as dependencies (again with names and paths
revised for a modern system).

Title:
  ghostscript fails to correctly substitute cidf fonts

Status in ghostscript package in Ubuntu:
  New

Bug description:
  I reported this bug first with ghostscript
  (http://bugs.ghostscript.com/show_bug.cgi?id=695874), but it is
  apparently a packaging issue.

  The general issue is that when there is a CIDF font in a .pdf that is
  not embedded in the document, ghostscript will stop processing the
  file at that font (see the file attached to the ghostscript bug).  The
  packaging issue is that CIDF fonts that are not on the system are in
  the default Ubuntu cidfmap file.

  System info is:

  $ lsb_release -a
  No LSB modules are available.
  Distributor ID: Ubuntu
  Description:    Ubuntu 14.10
  Release:        14.10
  Codename:       utopic

  $ ghostscript --version
  9.14
