Error in tolower(char_v) : invalid input

[oganm]

I am getting an error that suggests the package is successful in getting tweets in but fails at processing them.

Error in tolower(char_v) : 
  invalid input ' poor harry í ½í¸¢' in 'utf8towcs'

The "poor harry" is indeed one of my tweets but it seems to be having troubles with it. This is a windows machine so there might be some unexpected encoding issues

I'm getting the same error and I'm using Windows 10.

Looking at your error in the other issue, it seems like it could be about emojis

I have confirmed that this at least system specific. On an Ubuntu 16.04 everything worked just fine
