Long compilation time of crate "unicode-normalization" #55528

Hey folks,

I was told to create an issue here. When compiling crates, I often see this crate holding up the overall process, and because others are depending on it, it grabs one cpu core and the others are literally idle and I need to wait.

Yeah this contains some giant match statements which are slow. We could perhaps use something like phf_map here but that may not improve compile times.

I'd be thankful if there are some efforts to make it faster. :)
