When converting the attached PostScript file to PDF/A the output file contains squares instead of text. This was working fine in GS 8.7
Created attachment 7109 [details] PS file
Created attachment 7110 [details] PDF file
The embedded TrueType font is being set as non-symbolic when PDF/A is selected, which is never supposed to happen and certainly should not be happening for PDF/A output.
