How to remove unicode from string?

Answer 1

Instead of removing you should convert it to the appropriate format ... You have to set your local to UTF-8 like so:

Sys.setlocale("LC_CTYPE", "en_US.UTF-8")

Maybe you will see the following message:

Warning message:
In Sys.setlocale("LC_CTYPE", "en_US.UTF-8") :
  OS reports request to set locale to "en_US.UTF-8" cannot be honored

In this case you should use stringi::stri_trans_general(x, "zh")

Here "zh" means "chinese". You should know which language you have to convert to. That's it
