Somehow I got an invisible non-whitespace character into a line in a bash script file. It was causing all sorts of issues when I pasted the line into another program. Whitespace is set to show (View -> Active Editor) but this character is still invisible. When I open that file in TextWrangler it's visible as an upside down ?:
start.js ¿"./lib/da
I suspect I inserted a unicode character with the Control key by accident (OSX). How can I spot a character like this while I'm editing scripts in Webstorm?
