Unexpected characters in source code
On Google Chrome 65.0.3325.181 x64 (cohort: Stable), running JS V8 6.5.254.41 whenever I try to run something that includes jquery.flowchart (I've installed it as a dependency of my project using npm) I get multiple "SyntaxError: Unexpected identifier". All of them are due to characters which aren't displayed in editors, but are definetely not white spaces:

in Atom (or Notepad++, with the 'show all characters' option activated) there is nothing:

Simply deleting and re-typing a couple of charactes around the error is enough to remove the issues (and both Atom and Notepad++ detect a change, so there is definetely some character there).
So far, I've ecountered the issue at lines 240, 448, 709, 713, 800, 868 and 904
That is weird, I don't have this problem on my end. Are you sure you are using the last version of the plugin? getSelectedOperatorId should be now on line 800...
I've installed it via npm, so this could probably be fixed by updating the version provided by npm
