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:

Hi Dar,


I visited the URL and a few links (unfortunately the one that sounded most promising, "Guide to the Use of Character sets in Europe", returned "Page not found."); but my ignorance is not alleviated.

There is an alphabet for every language. There must be a way to filter keyboard input to reject keys that are not part of the alphabet, or a subset thereof.

This is not an issue of key translation between two computers; rather the focus is on filtering keyboard input on the user's computer to reject keystrokes that are defined as illegal for the current input field.
