2. Some softwares have the effect of hollow fonts.
For example, in Microsoft Word software, you can choose the effect of the font (menu: format-font) of the text: hollow.
Corresponding hollow characters can be obtained.
Photoshop can also easily get hollow characters through stroke processing.
Above, I hope it helps.
