Check If a Data Stream Is Possibly in UTF-8
The function checks whether given sequences of bytes forms a proper UTF-8 string.
stri_enc_isutf8(str)
str |
character vector, a raw vector, or
a list of |
FALSE means that a string is certainly not valid UTF-8.
However, false positives are possible. For instance,
(c4,85) represents ('a with ogonek') in UTF-8
as well as ('A umlaut', 'Ellipsis') in WINDOWS-1250.
Also note that UTF-8, as well as most 8-bit encodings, extend ASCII
(note that stri_enc_isascii implies that
stri_enc_isutf8).
However, the longer the sequence, the greater the possibility that the result is indeed in UTF-8 – this is because not all sequences of bytes are valid UTF-8.
This function is independent of the way R marks encodings in character strings (see Encoding and stringi-encoding).
Returns a logical vector. Its i-th element indicates whether the i-th string corresponds to a valid UTF-8 byte sequence.
