\title{Check If a Data Stream Is Possibly in UTF-16 or UTF-32}
\usage{
stri_enc_isutf16be(str)
stri_enc_isutf16le(str)
stri_enc_isutf32be(str)
stri_enc_isutf32le(str)
}
\arguments{
\item{str}{character vector, a raw vector, or
a list of \code{raw} vectors}
}
\value{
Returns a logical vector.
}
\description{
These functions detect whether a given byte stream is
valid UTF-16LE, UTF-16BE, UTF-32LE, or UTF-32BE.
}
\details{
These functions are independent of the way \R marks encodings in
character strings (see \link{Encoding} and \link{stringi-encoding}).
Most often, these functions act on raw vectors.
A result of \code{FALSE} means that a string is surely not valid UTF-16
or UTF-32. However, false positives are possible.
Also note that a data stream may be sometimes classified
as both valid UTF-16LE and UTF-16BE.
