Recommended way to convert case

[nmoreaud]

Hello
I wonder if this library provides a way to convert case to folded/upper/lower? Or to compare strings with insensible case?
If not, what would be the recommended way? ICU provides such a feature, but it is huge

This library does not provide support for case conversions. If you dislike ICU, I suggest looking at something like https://github.com/uni-algo/uni-algo
