UTF-8 Benchmark
The idea is to benchmark several utf-8 aspects of the Haskell Text package. Namely utf-8 encoding/decoding and various unicode casing operations. Hopefully, we'll find ways to improve text's performance.
For the time being, we're comparing the Text implementation with the C ICU one. In the future I also plan to test it against C++ Boost and the Rust stdlib.
