The following code will be able to handle multiple separator chars:

#fileName <- file name with fully qualified path
#separators <- each of them separated by '|'

read <- function(fileName, separators) {
    data <- readLines(con <- file(fileName))
    close(con)
    records <- sapply(data, strsplit, split=separators)
    dataFrame <- data.frame(t(sapply(records,c)))
    rownames(dataFrame) <- 1: nrow(dataFrame)

}
