This function converts input strings to ASCII, i.e. to character strings consisting of bytes not greater than 127.
stri_enc_toascii(str)a character vector to be converted
Returns a character vector.
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.
