Good points. I agree that there will never be a "perfect" solution, and
there will always remain enough room for misunderstanding, and even for
security problems.

This is not different from many other similar issues: there will never be
"the" perfect collation, or case conversion, or loose match.

This does not mean, however, that partial best-fit solution cannot be
