Hello guys,

we have noted a problem with Ghotstscript's Fontmap.GS file (from
Resource/Init/ folder).

This problem probably occurs only when the Fonts are not located in default
font path (/usr/share/ghostscript/Resource/Font), and they are located in other
system folder (/usr/share/fonts/urw-bas35/ in Fedora).

Here's the reproducer:

-------

NOTE: Important parts are highlighted like this.

-------

I have noted that the problem is (most likely) in Resource/Init/Fontmap.GS
file. There's remap of Helvetica-Narrow-Bold-Oblique to
NimbusSansNarrow-BdOblique:

-----------
% Aliases

<skipped>

/Helvetica-Narrow-BoldOblique /NimbusSansNarrow-BdOblique ;

-----------

/FontName /NimbusSansNarrow-BoldOblique def

===========

So, to conclude - the filename does not correspond to /FontName inside the T1
font itself.

After patching the Fontmap.GS, the font can be found and the *.eps file is
displayed correctly.

I'm attaching both the reproducer & patch.

My suggestion is to fix the Fontmap.GS (unless it breaks something for
vanilla-build usage of Ghostscript), and requesting the that (URW)++ company
renames the NimbusSansNarrow-BdOblique to NimbusSansNarrow-BoldOblique, so the
value of /Fontname corresponds to filename.

With the addition of changing the font file name, so it is consistent.
