One difficulty with fonts (and the reason I haven't made many) is the  
problem with ligatures, contextual variations, marks that need glyph  
positioning tables, etc. I do have an OlaeUni font which follows the  
CSUR submission (ftp://ftp.io.com/pub/usr/hmiller/fonts/ 
OLAEUNI_.TTF), although there are a couple of issues with it that  
would need OpenType features to implement, and OpenType doesn't work  
with Private Use scripts. Neesklaaz requires complex script  
processing, even beyond what OpenType tables provide, so my Neesklaaz  
font only works with SIL Graphite.

Not 100% sure what all that means, but how's this:

I think the characters should show up (they're all in the right
place).  There are two issues with OlaeUni font:

(1) There are a lot more characters than I included because you've
put them in non-private use areas, where other characters from
other scripts currently sit.  Was that intentional?

(2) My understand is that these ligature characters don't work
the way you want them to.  For example, on a Mac, I can "add"
an acute accent to an "e", but all I'm really doing is typing in a
code that tells the computer to display the "e-acute" cell.  The
glyphs you have that display over glyphs already typed should
work, but I don't *think* Unicode is supposed to be used to,
say, type an "n", and then type a "g", and then have it automatically
produce an "ng" ligature.  In order for that ligature to be available,
it must have a codepoint, and currently it doesn't.

I've installed the test version of the font on my machine, and
it doesn't seem to be working.  That is, I tested out one glyph
by putting it on a webpage.  I have unicode encoding up; the
glyph is at codepoint F072; I typed & # x F 0 7 2 ; onto the
page (no spaces); I have the font installed; I opened up the
webpage, and I get a square box.  Have I missed a step?
