I must find a way how to paint it. There is problem of some fonts - they didn't show correct width. PSpad paints standard content char by char. When I paint other occurences, I paint it as whole string and it causes difference.
The easiest way is to paint it same way as editor component. It will solve problem with all fonts. -- <https://forum.pspad.com/read.php?2,73355,73905> PSPad freeware editor https://www.pspad.com
