(* Conversions between bytes and characters, and between byte vectors
and strings (character vectors).
[byteToChar w] is the character corresponding to the byte w.
[charToByte c] is the byte corresponding to character c.
[bytesToString v] is the string whose character codes are the bytes
from vector v.
[stringToBytes s] is the byte vector of character codes of the string s.
In Moscow ML, all the above operations take constant time. That
is, no copying is done.
[unpackStringVec (v, i, NONE)] is the string whose character codes are
the bytes of v[i..length v-1]. Raises Subscript if i<0 or i>length v.
Equivalent to bytesToString(Word8Vector.extract (v, i, NONE)).
[unpackStringV (v, i, SOME n)] is the string whose character codes are
the bytes of v[i..i+n-1]. Raises Subscript if i<0 or n<0 or i+n>length v.
Equivalent to bytesToString(Word8Vector.extract (v, i, SOME n)).
[unpackString (a, i, NONE)] is the string whose character codes are
the bytes of a[i..length a-1]. Raises Subscript if i<0 or i>length a.
Equivalent to bytesToString(Word8Array.extract (v, i, NONE)).
[unpackString (a, i, SOME n)] is the string whose character codes are
the bytes of a[i..i+n-1]. Raises Subscript if i<0 or n<0 or i+n>length a.
Equivalent to bytesToString(Word8Array.extract (a, i, SOME n)).
[packString (ss, a, i)] copies the character codes of substring ss into
the subarray a[i..i+n-1] where n = Substring.size ss. Raises Subscript
if i<0 or i+n > length a.
Equivalent to Word8Array.copyVec{src=s, si=si, len=SOME n, dst=a, di=i}
when (s, si, n) = Substring.base ss.
