How do I fix problems with letters from a different alphabet on R?

Question

When I first wrote my script, letters such as 'ç' and 'ã - very commonly used in portuguese - were fine. So if I wrote, for example, the word 'vagão' in portuguese, that's how it would read it. But when I reopened the project with that script, it reads "vagão". How do I fix it?

You must be looking at encoding issues or conversion issues due to encoding on Windows(assuming that you're using windows). This might give you your answer.
