Wow thanks for taking time to give a very helpful explanation, looking back into the SFD file and I can now see the blackboard bold R and Z letters. There are three ways you can configure FOP to use custom fonts. One is to simply let it detect the fonts installed on your system, the second is to specify a folder where the fonts are held, and finally you can specify them individually. I have configured it so it looks into a specific directory e.g. "C:\FOP_Fonts". This folder then contains a "FreeSerif.afm" and "FreeSerif.pfb" file created via the "Generate Font" menu in Fontforge. As a test I created the following FO file which was taken from a simple “Hello World” example [1] with the simple addition of some extra characters and a font-family. <?xml version="1.0" encoding="UTF-8"?> <fo:root xmlns:fo="http://www.w3.org/1999/XSL/Format"; font-family="FreeSerif" font-weight="normal" font-style="normal"> <fo:layout-master-set> <fo:simple-page-master master-name="my-page"> <fo:region-body margin="1in"/> </fo:simple-page-master> </fo:layout-master-set> <fo:page-sequence master-reference="my-page"> <fo:flow flow-name="xsl-region-body"> <fo:block font-family="FreeSerif" font-weight="normal" font-style="normal"> Lj lj NJ Nj nj Ǎ ǎ Ǐ ǐ Ǒ ǒ Ǔ ǔ Ǖ ǖ Ǘ ǘ Ǚ ǚ Ǜ ǜ ǝ Ǟ ǟ Ǡ ǡ Ǣ ǣ Ǥ ǥ Ǧ ǧ Ǩ ℤ </fo:block> </fo:flow> </fo:page-sequence> </fo:root> When this is processed by FOP it generates a warning for the blackboard bold R letter: [WARN ] Glyph "Z" (0x2124) not available in font "FreeSerif". Since the FreeSerif font is embedded in the PostScript file I can run it through Adobe Distiller and get a PDF which contains the following: "Lj lj NJ Nj nj Ǎ ǎ Ǐ ǐ Ǒ ǒ Ǔ ǔ Ǖ ǖ Ǘ ǘ Ǚ ǚ Ǜ ǜ ǝ Ǟ ǟ Ǡ ǡ Ǣ ǣ Ǥ ǥ Ǧ ǧ Ǩ #" As you can see it managed to produce all the characters except for the blackboard bold Z which has been substituted by a hash. This seems to suggest it can find the FreeSerif font but the exported font doesn’t contain the blackboard bold Z letter. After viewing the font in another Font Manager (Fontforge is installed on another computer) I noticed the character map only contained 2,715 glyphs. This is a major reduction which might suggest I or Fontforge exported the font wrongly. I can attach the afm and pfb files but any idea what could have gone wrong?
