\alias{stri_escape_unicode}
\title{Escape Unicode Code Points}
\usage{
stri_escape_unicode(str)
}
\arguments{
\item{str}{character vector}
}
\value{
Returns a character vector.
}
\description{
Escapes all Unicode (not ASCII-printable) code points.
}
\details{
For non-printable and certain special (well-known,
see also R man page \link{Quotes})
ASCII characters the following
(also recognized in R) convention is used.
We get \code{\\a}, \code{\\b}, \code{\\t}, \code{\\n}, \code{\\v},
\code{\\f}, \code{\\r}, \code{\"}, \code{\'}, \code{\\\\}
or either {\\uXXXX} (4 hex digits) or {\\UXXXXXXXX} (8 hex digits)
otherwise.
As usual, any input string is converted to Unicode
before executing the escape process.
}
\examples{
stri_escape_unicode('a\u0105!')
}
