What are this "case modifier" and "diacritic modifier"?
If they are easy to type, this might be convenient.
If they are hard, I think the existing default is better for
handling case, and maybe for diacritics too.

Meanwhile, there is also the issue of discoverability.
If case-fold search required memorizing a special character,
most users would not memorize it and would never use it.
