Can we come up with a much simpler and safer variant that could
perhaps solve 85% of the problem? like perhaps only the letter-case,
and disregarding the Turkish issue somehow?  Then I could agree to
have that on the release branch.  The code on master is complex and
non-trivial, so having that on the release branch scares me.
