Latex solution : IEEE etc requiring all fonts to be embedded

Here's an ugly solution which worked for me
( this is from here just copying it here again in case the original post get lost in an internet purge )

modify file
/usr/share/gs-afpl/8.14/lib/gs_pdfwr.ps
and change lines

/.standardfonts [
/Courier /Courier-Bold /Courier-Oblique /Courier-BoldOblique
/Helvetica /Helvetica-Bold /Helvetica-Oblique /Helvetica-BoldOblique
/Times-Roman /Times-Bold /Times-Italic /Times-BoldItalic
/Symbol /ZapfDingbats
] readonly def

into

/.standardfonts [
% /Courier /Courier-Bold /Courier-Oblique /Courier-BoldOblique
% /Helvetica /Helvetica-Bold /Helvetica-Oblique /Helvetica-BoldOblique
% /Times-Roman /Times-Bold /Times-Italic /Times-BoldItalic
% /Symbol /ZapfDingbats
] readonly def

=========
the command pdffonts shows the different fonts and whether they are embedded
