stri_enc_fromutf32: Convert From UTF-32¶

Description¶

This function converts integer vectors, representing sequences of UTF-32 code points, to UTF-8 strings.

Usage¶

stri_enc_fromutf32(vec)

Arguments¶


`vec`	a list of integer vectors (or objects coercible to such vectors) or `NULL`s. For convenience, a single integer vector can also be given.

Details¶

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.

Value¶

Returns a character vector (in UTF-8). NULLs in the input list are converted to NA_character_.
