Description

This function converts input strings to ASCII, i.e., to character strings consisting of bytes not greater than 127.

Usage

Arguments

Details

All code points greater than 127 are replaced with the ASCII SUBSTITUTE CHARACTER (0x1A). R encoding declarations are always used to determine which encoding is assumed for each input, see stri_enc_mark. If ill-formed byte sequences are found in UTF-8 byte streams, a warning is generated.

A bytes-marked string is assumed to be in an 8-bit encoding extending the ASCII map (a common assumption in R itself).

Note that the SUBSTITUTE CHARACTER (\x1a == \032) may be interpreted as the ASCII missing value for single characters.

Value

Returns a character vector.
