stri_numbytes: Count the Number of Bytes
Counts the number of bytes needed to store each string in the computer’s memory.
character vector or an object coercible to
Often, this is not the function you would normally use in your string processing activities. See
For 8-bit encoded strings, this is the same as
stri_length. For UTF-8 strings, the returned values may be greater than the number of code points, as UTF-8 is not a fixed-byte encoding: one code point may be encoded by 1-4 bytes (according to the current Unicode standard).
Missing values are handled properly.
The strings do not need to be re-encoded to perform this operation.
The returned values do not include the trailing NUL bytes, which are used internally to mark the end of string data (in C).
Returns an integer vector of the same length as
