[Localization] request for information: how to get a .pdf file to use fonts on an XO

[jim]

greetings, 
   i hope you can provide me with a solution for the 
problem of presenting MOE books on an XO, this in 
support of Carol Ruth Silver's pilot program to support 
home schooling in rural Afghanistan. 
http://www.moe.gov.af/books.htm# 

   the Afghanistan Ministry of Education web site has 
various books, each of which is a directory with a 
front and back cover, table of contents, first section, 
second section, and a subdirectory called fonts in 
which there are several .ttf font files. 
   i've copied the entire set for a book (Pashto Books : 
Grade 1 : Math) to a Math subdirectory under the 
/home/olpc/ directory (XO 1, OS build 8.2.1), 

then as root i created a /usr/share/fonts/truetype 
directory and copied the fonts there, 

then i've run the fc-cache /usr/share/fonts/truetype 
command, 

then run the fc-list | sort command and saw the new 
fonts in the list. 

i edited the /home/olpc/.library/index.html files to 
add a link to one of the math sections, 

then i used the browser and clicked the link to the 
math section and got the file loaded but with empty 
rectangles rather than the fonts. 

how can i get the .pdf file to display with the fonts? 

is there a way to assemble the four .pdf files so that 
they are a single .pdf (can it be as simple as using 
the cat command)? 

my thanks,
