Scenario: you changed your computer and forgot to backup your font files. So when you opened PDF or SVG files most font types looked like Arial. You don’t have the font files to install. What do you do then?
Open the SVG file with Notepad then Ctrl + F “font-family”. You are going to see the name of the font used in your art.
Now you can google that font name, find it, download and use it, finally.
