This is strange. If the aspect of the body text changes, I assume you
properly configured the DejaVu fonts for FOP and didn't forget to
specify the config file on the command line:
fop -c config.xml math.fo math.pdf
Are you sure the font used for the text really is DejaVu (check the
properties of the PDF file in your viewer)?
Have you tried the jeuclid-user mailing list?


HTH,
Vincent
