How to safely remove Byte Order Marks (BOM) from files created on windows

October 15, 2017

The problem

If you read enough files created on a windows box you'll eventually run into this. ""\xEF\xBB\xBFyour expected string" instead of "your expected string". I recently ran into again while parsing some csv files exported in windows. In order to parse the string you'll need to remove what is called a Byte Order Mark.

Solution

Just search for "\xEF\xBB\xBF" and remove it.
