The SASLprep algorithm (RFC 4013)
This module implements the SASLprep string preparation algorithm, often used for normalizing passwords.
Note that SASLprep is SLOOOOOOW, and should really only be used on short strings like passwords.
This version of SASLprep doesn't check for unassigned codepoints.
Raised when a string cannot be transformed
val saslprep_a :
int array -> int array
Transform a string given as array of Unicode code points
val saslprep :
