Drawstring ( true) not clearing the background

Thanks.
Still trying to understand why this gives unknown font on my code

Modules.addCached("Font7x11Numeric7Seg",­function(){exports.add=function(a){a.pro­totype.setFont7x11Numeric7Seg=function()­{this.setFontCustom(atob("AAAAAAAAAAAAAA­EAAAAQAgBACAAAAHvQBgDAGAL3gAAAAAAAAAAHvA­AA9CGEMIYQvAAAACEMIYQwhe8AB4AIAQAgBA94AD­wIQwhhDCEDwAHvQhhDCGEIHgAAAgBACAEAHvAAe9­CGEMIYQveAA8CEMIYQwhe8AAABjDGAAAA96EEIIQ­Qge8AB7wIQQghBCB4AD3oAwBgDAEAAAAPAhBCCEE­L3gAPehDCGEMIQAAAe9CCEEIIQAAAAAAAA"),32,­atob("BwAAAAAAAAAAAAAAAAcCAAcHBwcHBwcHBw­cFAAAAAAAABwcHBwcH"),11)}}}); 
// Load fonts 
require("Font7x11Numeric7Seg").add(Graph­ics); 
Bangle.setLCDTimeout(40); 
 
function myFunction(txt) {   
  g.reset(); 
  g.setFont("Font7x11Numeric7Seg",4);   
  g.setFontAlign(0,0);  
  g.drawString(txt, 130, 120, true); 
} 
 
g.clear(); 
 
myFunction("12:20");
