stri_numbytes: Count the Number of Bytes
In stringi: THE string processing package for R

Description Usage Arguments Details Value See Also Examples

Counts the number of bytes needed to store all the characters of each string in computer's memory.

1	stri_numbytes(str)

str

character vector

This is often not the function you would normally use in your string processing activities. See rather stri_length.

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 represented with 1-4 bytes (according to the current Unicode standard).

Missing values are handled properly, as opposed to the built-in nchar(str, "bytes") function call.

The strings do not need to be re-encoded to perform this operation.

The returned values does not of course 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 str.

Other length: stri_isempty; stri_length

stri_numbytes(letters)
stri_numbytes(c('abc','123','\u0105\u0104'))

# this may fail on Windows, as there is no native support for 4-bytes
# Unicode characters; see, however, stri_escape_unicode():
stri_numbytes('\U7fffffff') # compare stri_length('\U7fffffff')
