I sometimes work with transliterations of cuneiform. I don't want s to match š, h to match ḫ, g to match g̃, r to match ř, or any accented vowels matching any differently accented or unaccented vowels. They mean drastically different things. If you're going to have a "smart" search that decides to mesh these together, the option to turn off the "smartness" should be right there.
