The answer goes out to Rushabh. You can use iconv which converts the strings with one encoding to another and substitutes nonconversable charaters with the value given in argement sub:

foo <- "à®…à®©à¯à®ªà¯à®®à¯ à®ªà®¾à®šà®®à¯à®®à¯ à®¨à®¿à®±à¯ˆà®¨à¯à®¤ à®‡à®¸à¯à®²à®¾à®®à®¿à®¯ à®šà®•à¯‹à®¤à®° à®šà®•à¯‹à®¤à®°à®¿à®•à®³à¯ à®•à¯à®•à¯ à®°à®®à¯à®œà®¾à®©à¯ à®¨à®²à¯à®µà®¾à®´à¯à®¤à¯à®¤à¯à®•à¯à®•à®³à¯ â€¦"
iconv(foo, from = "UTF-8", to = "ASCII", sub = "")

Output:

[1] "aaaaaaa aaasaaaa aaaaaaa aaaaaaaa asaaaa asaaaaaaaa aaaa aaaaaaa aaaaaaaaaaaaaaaa a"
