non printing characters change with TSCu_Comic font

Just installed TSCU_Comic font. When I assign the font, the non printing characters change too. Is there a way to avoid that?

The Metric of “Non-Printing-charakters” belongs to the Fontproperties, there is no way except with weird search and replace

maybe →search for ( |\t) (with Option regular Expression) →→findall.
and reduce the Font-Size of Found
