Am R newbie. Am using Mac OSX 10.9.5 and R Studio Version 0.98.1056

Am trying some R script to conduct sentiment analysis on tweets. When I run the R script i get errors such as the one below as i try to sentiment score some tweets.

Error: invalid input ...followed by the tweet in quotes which always includes �� at the point the person used an emoji.

I believe the error is caused because the original tweet contains emoji and R is not sure what to do at that point. I am trying to figure our what R code should be used to remove / ignore emoji as i set up the file for processing.

Any tips or links to how others have solved this are appreciated.
