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 NULLs. For convenience, a single integer vector can also be given.

Value

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

Details

UTF-32 is a 32bit encoding in which each Unicode code point corresponds to exactly one integer value.

This function roughly acts like 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 incorrect code point is given, a warning is generated and a 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.
