Perhaps the reason you are having trouble finding info on high-order 
ASCII is that there is no high-order ASCII as obnoxious purists like me 
are quick to point out.

Here is a document that has helped me get my bearings on character code 
issues:

You might be interested in using ISO-8859-1 which includes ASCII as a 
subset and does define higher-end coding.  Or the characters in common 
of 1-byte (in UTF8) Unicode and ISO-8859-1.  Or limit yourself to those 
in common of those and some other ISO-8859.

I wonder if there are keyboard standards for Unicode...
