> Some Arrow functions will fail if e.g. the CPU doesn't have the right instruction set extensions (e.g. POPCNT on x86 - see ARROW-5381). We may want to provide a global function that checks requirements and/or otherwise initializes Arrow internal structures (the single one I can think of is `InitializeUTF8()` in `util/utf8.h`).
