\title{Check If a Data Stream Is Possibly in ASCII}
\usage{
stri_enc_isascii(str)
}
\arguments{
\item{str}{character vector, a raw vector, or
a list of \code{raw} vectors}
}
\value{
Returns a logical vector.
Its i-th element indicates whether the i-th string
corresponds to a valid ASCII byte sequence.
}
\description{
The function checks whether all bytes in a string are in the set {1,2,...,127}.
}
\details{
This function is independent of the way \R marks encodings in
character strings (see \link{Encoding} and \link{stringi-encoding}).
