Thanks Koji.  I played with it a little.

I may find a use for it, but I'd still prefer to update Ahem.  Reasons 
include, but are not limited to, it's often useful to have blanks where 
the spaces are, as Ahem does, and it's particularly useful to have the 
wall-to-wall painting of the space that Ahem offers, so that you can 
compare shapes simply.  I also found that it doesn't support script such 
as arabic or complex scripts, where the glyphs change according to 
context - in Ken's font you just see the arabic text in a different font.

But good to know about.


Also, i'll probably uninstall it because it seems to be taking a higher 
priority than other fonts on my system for certain scripts when no font 
is specified for the page, which is annoying. For example, i can no 
longer see Thai Tham text, even though I have a font for it - all i see 
are the boxes with triangles :(  Maybe there's a way to prioritise fonts 
on your system, but i'm not aware how?
