How do you do the checking?

I've been asked by the user to eliminate similar characters. However,
I suspect that his list of characters is not exhaustif. I would put
these characters in a string, then use %XLATE to see if the name
entered contained one of these characters. Although I think we've now
limited our users to using only capital letters AtoZ plus spaces in
between, so maybe it'd be easier to control what can be used instead
of what can't. But then %XLATE wouldn't work, would it?

You might be able to use %CHECK. Build a string of _valid_ characters, and %CHECK will tell you the first character that isn't in that string.

validChars = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ ';
testString = 'A?B';
firstBad = %check(validChars : testString);
// firstBad = 2

Capital letters A-Z might not be sufficient though. What about valid characters like É and Ç? (E accent egu, C cedille)
