stri_enc_fromutf32: Convert From UTF-32¶
This function converts integer vectors, representing sequences of UTF-32 code points, to UTF-8 strings.
a list of integer vectors (or objects coercible to such vectors) or
UTF-32 is a 32-bit encoding where each Unicode code point corresponds to exactly one integer value.
This function is a vectorized version of
intToUtf8. As usual in stringi, it returns character strings in UTF-8. See stri_enc_toutf32 for a dual operation.
If an ill-defined code point is given, a warning is generated and the corresponding string is set to
NA. Note that
0s are not allowed in
vec, as they are used internally to mark the end of a string (in the C API).
See also stri_encode for decoding arbitrary byte sequences from any given encoding.
Returns a character vector (in UTF-8).
NULLs in the input list are converted to
