That's up to 8388608 addresses lost...
Could someone explain this? I feel like I'm missing something (not the 2^16 addresses, the "#unicode code points")
edit: From wikipedia:
"Unicode comprises 1,114,112 code points in the range 0x0 to 0x10FFFF. The Unicode code space is divided into seventeen planes (the basic multilingual plane, and 16 supplementary planes), each with 65,536 (= 216) code points."
