\alias{checkUTF8}
\title{
Check the validity of a byte stream ot be interpreted as UTF8.
}
\description{
\code{checkUTF8} check whether a given raw vector can be used as a
valid string encoded in UTF8.
}
\usage{
checkUTF8(what, quiet = FALSE, charlen = FALSE, min.char = 1L)
}
%- maybe also 'usage' for other objects documented here.
\arguments{
\item{what}{raw vector with the payload}
\item{quiet}{logical, if \code{TRUE} then the function will not fail
but report success/failure via its result, otherwise failures are
considered errors.}
\item{charlen}{logical, if \code{TRUE} then the function returns the
length of the longest byte sequence representing a character in the
file.}
\item{min.char}{integer, any bytes below this value are considered
control chacters and reported as errors. The default value of 1L
guards against strings including NULs.}
}
\value{
If \code{charlen=FALSE}: \code{TRUE} on success, \code{FALSE} if the
payload is invalid and \code{quite=TRUE}.
If \code{charlen=TRUE}: positive integer corresponding to the
longest encoded sequence on success, negative integer on failure.
