I can't duplicate this. In my site-font I have the Google Tinos fonts with 
just four entries in the download file. In the system font directory, the 
download file has this entry:-

        FreeEuro        ../devps/freeeuro.pfa

Plus all the other pdf fonts. It also has many other esoteric fonts, like:-

        3Of9Barcode     3OF9.pfa

If I test using TinosR and the glyphs \[eu] and \[Eu], both are visible (but 
different). If I then switch font to 3of9 it prints the barcode.

If I do the same but using -T ps the \[eu] and the barcode is missing. 
Interestingly, if I change the font to TR rather than TinosR so that groff is 
only using the system font directory it still reads the site-font download 
file, so it fails.

I think the rule of thumb is that if you use site-font for devps do not change 
anything in the system directory, whereas for devpdf the two directories can 
be treated separately, you should not be copying stuff from the system 
directory to the site directory for gropdf.

If you still find you need to copy stuff from system to site on your setup, 
please can you zip up both directories so I can investigate.

If, after installing a new version of groff, any of the font files were 
different in the system directory you may see anomalies. It is safer not to
