Instead of using a bitmap font directly, you could create a bitmap-file (in
MSPaint), type in all the characters there and save it to a BMP-file. In your
program that needs to display the characters, just load the BMP-file and blit the
appropriate region for a character to your window.

Hi Craig

http://babel.uoregon.edu/yamada/fonts.html

i keyed in "font library" in my search engine . 
the above is one of the results. it also has Klingon.
there is some places that have free fonts too.

divide the problem and conquer.
3000 / 10 chars/day = 300 days / 10 people = 30 days.

look out : i am thinking again.
 how the characters are built?
is there actually only 16 different pen strokes?
save only the different strokes first and then have everybody
chip in to build the characters. it would probably have to be local people
who are looking at the same data (book?) you have.

Thanks Rudy,

The issue for me is not availabilty of fonts. I have plenty of Japanese 
fonts. It's how to render a bitmap font in my Euphoria application.

You can simply write a True-Type font to a bitmap in RAM and then render
that on the screen. Here is starting point for you. It creates 26 bitmaps,
from "A" to "Z" in Times New Roman font at 200 point.

----------------------
without warning
include win32lib.ew

constant pm = create(Pixmap, "", 0, 0,0, 1,1, 0)
procedure DoLetter(sequence pText)
    sequence lTextRect
--    printf(1, "%s\n", {pText})
    lTextRect = getTextExtent(pm,pText)
    setCtlSize(pm, lTextRect[3], lTextRect[4])
    setBackColor(pm, BrightWhite)
    setPenColor(pm,Black)
    wPuts({pm, 0, 0}, pText)

    VOID = copyToBitmapFile(pm, pText[1] & ".bmp", 0, 0, 
                            lTextRect[3], lTextRect[4])

end procedure

setFont(pm, "Times New Roman", 200, 0)
for i = 'A' to 'Z' do
    DoLetter({i})
end for

Because, as I understand it, Linux has underlying support for double-byte
characters. Not all versions of Windows do. Windows 98, as I mentioned I'm
using, doesn't. You can install add-ons that provide that support, but 
only in Office applications, so that excludes anything written in Euphoria.

See above ... and bitmaps work, so I'm only seeking a working solution.

Craig:

  This code that will create xpm constants for
  the bdf files. It comments out the other file lines.
  so you can keep the comments for the copyright and
  other wanted information by editing the file and
  removing what you don't want. This code will genertae
  the code to allow you to use the win32lib or my w32engin.ew
  library.
