It looks a bug in sdfdot.

The date in head created below errors:

The date has to be removed from the dot file to create a pdf file.
I also had to change fontname to Courier to make it display properly.

How to embed fonts

Some applications such as Adobe InDesign automatically embed all fonts when pages are exported to PDF.

Acrobat Distiller offers an option to automatically add missing fonts to PostScript files it has to process. In the font locations menu, the user can define several folders that have to be searched for fonts that are missing in the PostScript file. Distiller only needs the printer fonts, it does not need the screen fonts.

Fonts that are not necessarily included in PDF files

Older versions of Adobe Acrobat (Acrobat 3.x and earlier) will never embed the following 14 fonts in a PDF file:

• Courier, Courier-Bold, Courier-Oblique & Courier-BoldOblique
• Times-Roman , Times-Bold , Times-Italic & Times-BoldItalic
• Helvetica, Helvetica-Bold, Helvetica-Oblique & Helvetica-BoldOblique
• Symbol
• ZapfDingbats.

These fonts, excluding ZapfDingbats, are called the Base 13 fonts.

From Acrobat 4.x onwards, there is no problem embedding the above 14 fonts. In fact it is a good idea to actually always embed these fonts as well. Instead we got another restriction: if the licensing policy of a TrueType forbids the font to be included in a file, Distiller 4 and later will respect this restriction and will not embed the font.
