I find the stringi package works well for this sort of thing, e.g.,
library(stringi)
x <- c("!", "\"", "#", "$", "%", "&", "'", "(", ")", "*", "+", ",",
+ "-", ".", "/", "0", "1", "2", "3", "4", "5", "6", "7", "8", "9", ":",
+ ";", "<", "=", ">", "?", "@", "A", "B", "C", "D", "E", "F", "G", "H",
+ "I", "J", "K", "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V",
+ "W", "X", "Y", "Z", "[", "\\", "]", "^", "_", "`", "a", "b", "c", "d",
+ "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r",
+ "s", "t", "u", "v", "w", "x", "y", "z", "{", "|", "}", "~", "-", " ",
+ "¡", "¢", "£", "¤", "¥", "¦", "§", "¨", "©", "ª", "«", "¬", "", "®",
+ "¯", "°", "±", "²", "³", "´", "µ", "¶", "·", "¸", "¹", "º", "»", "¼",
+ "½", "¾", "¿", "À", "Á", "Â", "Ã", "Ä", "Å", "Æ", "Ç", "È", "É", "Ê",
+ "Ë", "Ì", "Í", "Î", "Ï", "Ð", "Ñ", "Ò", "Ó", "Ô", "Õ", "Ö", "×", "Ø",
+ "Ù", "Ú", "Û", "Ü", "Ý", "Þ", "ß", "à", "á", "â", "ã", "ä", "å", "æ",
+ "ç", "è", "é", "ê", "ë", "ì", "í", "î", "ï", "ð", "ñ", "ò", "ó", "ô",
+ "õ", "ö", "÷", "ø", "ù", "ú", "û", "ü", "ý", "þ", "ÿ")
