Oops 1: should be "${GS_LIB}/Encoding/ISOLatin2Encoding" for user 
Oops 2: The Windings file is not DSC-marked either.
Oops 3: Having anything in "${GS_LIB}/Encoding" causes a fatal error [2].  I
reopen for this reason, since your advice does not seem to work.

BTW, the documentation "Finding PostScript Level 2 resources" [1] is incorrect
in that Ghostscript does not apply the '../Resource' infix to the local path
and user path.

Instead of:

If the value of the system parameter GenericResourceDir is not an absolute
path, Ghostscript assumes multiple resource directories. In this case it
concatenates : 

  1.
A directory listed in the section How Ghostscript finds files, except the
current directory; 

  2.
The value of the system parameter GenericResourceDir; 

  3.
The name of the resource category (for instance, CMap); 

  4.
The name of the resource instance (for instance, Identity-H)


Should be:

If the value of the system parameter GenericResourceDir is not an absolute
path, Ghostscript assumes multiple resource directories. In this case it
concatenates : 

  1.
A directory listed in the section How Ghostscript finds files, [-except the
current directory-]; 

  2. 
The value of the system parameter GenericResourceDir, [+except for the current
directory and for "${GS_LIB}"+]; 

  3.
The name of the resource category (for instance, CMap); 

  4.
The name of the resource instance (for instance, Identity-H)If the user doesn't
set the system parameter GenericResourceDir, Ghostscript creates a default
value for it with attaching the string ../Resource to directory paths explained
in How Ghostscript finds files, except the current directory. The first
successful combination is used.
