The operating system is freebsd and after installation I receive this error:

prince: warning: no glyphs for character U+0050, fallback to '?'
prince: internal error: no fallback glyph for character U+0050

Is this a problem with the input data?

How do I find out where this character is?

Thanks, Evan

U+50 is the Latin letter "P". In this case it means you don't have any fonts installed on this machine. You need to install some fonts, or if you already have some installed tell Prince about them.

Are these the fonts I should be using?
The font directory has:

No, these are all bitmap fonts (for X-Windows?). You need some TrueType fonts, with a .ttf or .otf extension. For example, the Microsoft Core Fonts, or the DejaVu fonts, or Liberation fonts.

Thanks for taking the time to help. I just installed the following:
-rw-r--r-- 1 546 546 9345992 Jan 11 2005 cwfs.ttf
-rw-r--r-- 1 546 546 5493164 Jan 11 2005 cwheib.ttf
-rw-r--r-- 1 546 546 10664536 Jan 11 2005 cwkai.ttf
-rw-r--r-- 1 546 546 11929748 Jan 11 2005 cwming.ttf
-rw-r--r-- 1 546 546 142538 Jan 11 2005 cwttf-cjk-bl.pdf
-rw-r--r-- 1 546 546 150291 Jan 11 2005 cwttf-ooo-bl.pdf
-rw-r--r-- 1 546 546 7853544 Jan 11 2005 cwyen.ttf

the problem if that I am not sure which file to use and how. Would the following work?
@font-face {
font-family: sans-serif;
font-style: normal;
font-weight: normal;
src: url("/usr/ports/x11-fonts/urwfonts/cwyen.ttf")
}

Something like this will work, although it is best to define the default "serif" font that Prince will fall back to when other fonts cannot be found, and these font files appear to be primarily CJK (Chinese, basically). You can run "prince --scanfonts /usr/ports/x11-fonts/urwfonts/*.ttf" to get @font-face rules for them. Are there any other font packages for FreeBSD, like the DejaVu fonts, which are good for Latin text?

THANKS!!!

I installed the dejavu fonts, edited th efonts.css file and now I continue with looking into page numbering and such.

Thanks for the help.
