\title{Return the 8 digits of a CEP, accepting the mask}
\usage{
normalize_cep(value)
}
\arguments{
\item{value}{A length-one character vector. Numbers are rejected on
purpose: \code{1001000} has already lost the leading zero that makes
\code{"01001000"} a CEP. Convert with \code{sprintf("\%08d", x)} first.}
}
\value{
The 8 digits, as a length-one character vector.
}
\description{
\code{"01001-000"}, \code{"01001000"}, \code{"01001.000"} and \code{" 01001-000 "} all become
\code{"01001000"}.

This runs \strong{before} any request: a 7-digit CEP is the caller's bug, and
spending a round trip for the server to say so wastes both sides' time.
}
\section{Conditions}{

Signals \link[=cepis_conditions]{cepis_invalid_cep} unless exactly 8 digits
remain.
