SYS-UTFBYTES(2)SYS-UTFBYTES(2)NAME
utfbytes - compute UTF length of complete Unicode characters in a UTF
byte sequence
SYNOPSIS
include "sys.m";
sys := load Sys Sys->PATH;
utfbytes: fn(buf: array of byte, n: int): int;
DESCRIPTION
Utfbytes examines the n-byte UTF sequence in buf and returns the number
of bytes representing complete Unicode characters. The value will be
less than n when the region inspected ends with an incomplete UTF
sequence.
DIAGNOSTIC
A bounds check error results if n exceeds the length of the array.
