It’s great news if memcpy is now fast enough. I’d love to see my old awkward optimization removed if it no longer does any good.

In fact, I’m not sure we need a copyChars function at all. We could use memcpy directly as we once did, or even better ICU has u_memcpy if we want something that prevents the need to do "* sizeof(UChar)" at each call site. As long as u_memcpy has great performance too; presumably it expands into memcpy as an inline.
