I tried using sorting in Footables. It works fine except that the sort icon indicators in the header is not showing properly(it looks like a garbled character). It seems to be an encoding issue.
Here are the css that I included
footable.core.min.css
footable.metro.min.css
Here are the scripts that I included
footable.js
footable.filter.js
footable.paginate.js
footable.sort.js
Is there something I am missing?
