R: Convert To ASCII

stri_enc_toascii {stringi} | R Documentation

## Convert To ASCII

### Description

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

### Usage

    stri_enc_toascii(str)

### Arguments

`str` | a character vector to be converted

### 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.
