Change charset of webserver / touchbar to UTF-8

Describe the bug
Hi, unfortunately when updating the widget with some accent characters (ąśżźćółę for example), BTT widgets does not update. I'm not sure whether this is a fault of touchbar or webserver, probably webserver.

Affected input device (e.g. MacBook Trackpad, Magic Mouse/Trackpad, Touch Bar, etc.):
Touchbar, webserver

Sorry, did not realize that I havn't added my setup:

  • Type of Mac: mbp 13" mid 2014
  • macOS version: 10.13.5
  • BetterTouchTool version: 2.517 alpha
