stri_enc_toascii: 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

Value

Returns a character vector.

Details

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

A bytes-marked string is assumed to be represented by a 8-bit encoding such that it has ASCII as its subset (a common assumption in R itself).

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