If you know the encoding of the string, or if its encoding is thecurrent locale encoding, then you can use the iconv function to convertthe string to ASCII. Something like: iconv(accented.string, to="ASCII//TRANSLIT")While 7-bit ASCII does not permit accented characters, extended (8- bit)ASCII does. Hence, I'm not sure this will work. But it's worth a try.

[1] "a" "e" "i" "o" "u" "A" "E" "I" "O" "U" "a" "e" "i" "o" "u" "y"
"A" "E" "I" "O"
[21] "U" "Y"Notice that the accent acute gets converted to a single quote and therefore needs to be dbl-\-ed to get recognized in an R regex pattern.
