All I am implementing at the moment is a string-level check.

But a character level check would be much better. I don't think there is 
anything stopping us from having both, and selecting the version from 
the command line, if that were the issue.

Actually, for optimal performance the best approach would presumably be 
to first validate with the string-level implementation, then check char- 
by-char if that fails to get specific positional diagnostics.
