I just use screen copy program, or snip-it.
You can still copy and paste with the PNG font. The problem is the SVG font. An SVG image requires an application that understands SVG.
However, I have a fix for this that I should have done tomorrow. It converts the SVG font to a PNG image. This way you get the quality of the SVG but the simplicity of using a PNG. This fix has already been installed for the customize sign page.
