Summary0005953: String length in oct2str and oct2char predefined functions
DescriptionThe textual description of the functions mentions just "length" without specifying what does it mean (i.e. no. of characters or what lenghtof would return).

Proposed solution (different per function):
C.23 Octetstring to character string
...
"The resulting charstring shall have the same length as the incoming octetstring." -> "The resulting charstring shall have the same number of characters as the incoming octetstring."

C.24 Octetstring to character string, version II
...
"The resulting charstring shall have the same length as the input octetstring." -> "The resulting charstring shall have the same string length (what lenghtof would return) as the input octetstring."

I don't think that

"The resulting charstring shall have the same string length (what lenghtof would return) as the input octetstring."

would be correct as lengthof returns half the number of characters for octetstrings while for charstrings, it is obviously the number of characters.

For C.24 it is OK, but your explanation and the proposed text are contradicting for C.23; take the example from the standard: oct2str('4469707379'O) = "4469707379"
lengthof('4469707379'O) -> results 5
lengthof("4469707379") -> results 10
lengthof doesn't return the same value for the octet~ and charstrings.

Oh, I retract my comment as the proposal was about the oct2char function where, of course, lengthof(oct2char(xxx)) == lengthof(xxx)

I would propose:

C.23: "The resulting charstring shall have double as many characters as the input octetstring has octets."

C.24: "The resulting charstring shall have as many characters as the input octetstring has octets."
