Description
This routine returns the number of characters found in the input string
up to the position specified by len. All one-byte
7-bit control characters and one-byte 8-bit characters (e.g. an 8-bit
character followed by a 7-bit control character) are treated as a
character. If the last character specified by len is a
multi-byte character with its last byte located beyond the input string
terminating position as specified by len, this
multi-byte character is also counted by the routine.

This routine returns the number of characters found in the input string
up to the position specified by the length field of the descriptor. All
one-byte 7-bit control characters and one-byte 8-bit characters (e.g.
an 8-bit character followed by a 7-bit control character) are treated
as a character. If the last character specified by the length field of
the descriptor is a multi-byte character with its last byte located
beyond the input string terminating position, this multi-byte character
is also counted by the routine.
