There is some kind of problem in the Vectric Vcarve Desktop editor with the “Stick” fonts mentioned above. When adding a text object, Vcarve has a choice between TrueType or Single Line. These fonts are installed as TrueType fonts and don’t show up in Windows as Single Line fonts, although they function as single line fonts when carved.
Normal letters/numbers don’t indicate a problem, but most other characters won’t display or display a “!” character. The way to make them display correct characters (for me) has always been to change the option from TrueType to Single Line and back. Don’t change the font selection, just change and change back. That’s when the characters typed will be displayed.
I don’t know why that happens. AFAIK its Windows.
