But Tom, for many purposes, forms, and language-script
combinations, toLowerCase() is _exactly_ the right thing. For
others, if one adopts the principle of doing no harm, whether
toLowerCase() or toCaseFold() are likely to do less harm depends
on some rather subtle issues including the perspective from
which "harm" is viewed.
I think one could more accurately restate your comment above as
"... to understand that toLowerCase() is sometimes not the right
thing and that sometimes toCaseFold() is sometimes not the right
thing either.
I could take a shot at a paragraph explaining that if it is what
people want. Otherwise, I'd be very careful about getting
further into that space than the present text goes. Personally,
I think the text is still dancing around the issue too much,
rather than addressing it, but I may be in the rough.
