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

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.
