How shall we know this?  The file starts with

  %!PS-Adobe-3.0 Resource-CMap
  %%DocumentNeededResources: ProcSet (CIDInit)
  %%DocumentNeededResources: CMap (90pv-RKSJ-UCS2C)
  %%IncludeResource: ProcSet (CIDInit)
  %%IncludeResource: CMap (90pv-RKSJ-UCS2C)
  %%BeginResource: CMap (90pv-RKSJ-UCS2)
  %%Title: (90pv-RKSJ-UCS2)
  %%Version: 4.002

This makes it look like a valid CMap file.

Where can I get a list of cmap-like files specific to Acrobat?

To avoid future confusion, I strongly suggest to put a comment into
the pseudo-cmap file.
