You don’t receive a special font file when you purchase a license. You are only buying a license to use the font(s) for profit. My fonts are free to download HERE
Some of my fonts have ‘Demo’ in the title. There is no special version of these files with extra characters. You can download the version with Demo removed from the title HERE
Please download, install, and test the font(s) before purchasing a license to ensure that they work for your intended use.
