Affinity Desginer Windows: How change this (or need special font) when IJ type in fixed width fonth IJ uses smaller space than JI? i imagined Courier for exampel should uses fixed size letters. i know only one word what has this but still. i want know is this font or not? if not found how change. anbd if font how found what dont do this.
i found solution is text field Charter settihngs->Typography->firest button what is called in help what comes when pointer stays mont stanard standard ligatures disabling this does what i wanted.
