It's not generally a compiler thing, it's an OS interpretation thing.
'\r' is a character called Carriage Return - because in the days of teletypes that is what it did, it moved the carriage (i.e. print head) to the left hand side of the paper.
Different system interpret what it does differently: some move the cursor to the far left, some move it to the left and down a line.

If you can, and you want to be portable, avoid using it directly - declare a constant instead so you cna change it if you need to.
