; function utf8-to-cps (cps = codepoints)
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; This function decodes UTF-8 information supplied as bytes in argument u
; and uses the argument res to store the array of codepoints
; (integers >= 0  and < 10FFFFh); the space for this array should have been
; allocated by the caller; an upper limit for the size of the array in bytes

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Example program to demonstrate sharing public keys from CryptoApi to CNG

Note: Reversing the process would allow sharing public keys from CNG to 
CryptoApi.  You would need to be careful of padding parameters and 
versions.
