But strlen() works only for zero-terminated strings in multi-byte
encodings. It will fail on wide character encodings such as UTF-16 and
UTF-32. And wcslen() is probably also of no help if you have a byte
array, not a wchar_t array.
On the other hand, I have great difficulty to envision a real-world
situation, where the user of iconv
- knows that the input is zero terminated
- does not know whether this is an 8-bit, 16-bit or 32-bit
wide and aligned zero
which is the situation it seems to me Michael might refer to.
So the question to Michael is: What is the actual problem you want to
solve?
