GhostScript font issues

I'm running GPL Ghostscript 8.70 (2009-07-31) on Windows XP. I have about 100 PDF files I've attempted to run through GS, but I'm having font-related issues on two separate groups of files from two different customers. I'm not sure if the issues could be related. Here are the two errors I receive:

    Loading Courier font from C:\Program Files\gs\fonts/cour.ttf... 2343384 986555 13583240 开发者_高级运维12261829 3 done.
    Using CourierNewPSMT font for Courier.
    Error: /rangecheck in --get--

Can't find CID font "Arial".
Substituting CID font /Adobe-Identity for /Arial, see doc/Use.htm#CIDFontSubstitution.
The substitute CID font "Adobe-Identity" is not provided either. Will exit with error.
Error: /undefined in findresource

I've tried just about everything I can think of with fontmap and cidfmap. Does anyone out there have a solution?

Taken from Ghostscript Bug Report:

First I tried to edit the cidfmap file adding following lines there:

/Arial-BoldMT           << /FileType /TrueType /Path 
(C:/WINDOWS/Fonts/ARIALBD.TTF)  /SubfontID 0  /CSI [(Unicode) 0] >> ;
/Arial-ItalicMT         << /FileType /TrueType /Path 
(C:/WINDOWS/Fonts/ARIALI.TTF)  /SubfontID 0  /CSI [(Unicode) 0] >> ;
/ArialMT                << /FileType /TrueType /Path 
(C:/WINDOWS/Fonts/arial.ttf)  /SubfontID 0  /CSI [(Unicode) 0] >> ;
/TimesNewRomanPSMT      << /FileType /TrueType /Path 
(C:/WINDOWS/Fonts/timesi.ttf)  /SubfontID 0  /CSI [(Unicode) 0] >> ;

This will allow the document to be rendered correctly but symbols were not readable, I tried to play with encoding setting but no luck, same unreadable symbols displayed.

Then I to defined a small dictionary:

/tempfontsdict 1 dict def tempfontsdict 
begin 
 /Arial-BoldMT       (C:/WINDOWS/Fonts/ARIALBD.TTF)  def
 /Arial-ItalicMT     (C:/WINDOWS/Fonts/ARIALI.TTF)  def 
 /ArialMT            (C:/WINDOWS/Fonts/arial.ttf)  def 
 /TimesNewRomanPSMT  (C:/WINDOWS/Fonts/timesi.ttf)  def 
End

And changed the pdf_font.ps:

       dup /FontFile knownoget not {
          dup /FontFile2 knownoget not {
            dup /FontFile3 knownoget not {
                %//null                 

    +           dup /FontName get 
    +           /tempFontName exch def
    +           tempfontsdict tempFontName known {
    +               dup /FontName get (Custom font change:) 
print == 
    +               tempfontsdict tempFontName get
    +               /tempFontFile exch def          

    +               dup /FontFile3 << /F tempFontFile >> 
put                      
    +               dup /FontFile3 get
    +           } {
    +               //null
    +           } ifelse                
            } if
          } if
        } if

This solved the problem but doesn’t look like a good solution for the issue.

Note: Always Keep the GS updated to latest version the current version is 9.50.

Got the same problem. Solved changing from the gs 8.70 from the package manager to the gs 9.50 (AGPL Release) provided from https://ghostscript.com/download/gsdnld.html
