Convert Characters to ASCII

Description

Convert character vector to ASCII, replacing non-ASCII characters with single-byte (x00) or two-byte (u0000) codes.

Usage

ASCIIfy(x, bytes = 2, fallback = "?")

Arguments

Value

A character vector like x, except non-ASCII characters have been replaced with x00 or u0000 codes.

Note

To render single backslashes, use these or similar techniques:

    write(ASCIIfy(x), "file.txt")
    cat(paste(ASCIIfy(x), collapse="\n"), "\n", sep="")

The resulting strings are plain ASCII and can be used in R functions and datasets to improve package portability.
