Yes, the solution I proposed addresses only symbols, not the more-general
problem of confusable characters in strings and characters. Although symbols are
a more significant issue since they occur more often, it would be nice to
address strings and character constants too. We can do that by adding support
for a new string escape \cX for the confusable character X (e.g., ?\c՚ would
mean U+055A ARMENIAN APOSTROPHE), and by diagnosing the use of unescaped
confusable characters in strings and character constants.
