Give the system a few moments to download the font in the background, and the warning should disappear. Step 3: Track Down the Original Source
In an ideal digital typographic environment, every document would render exactly as the author intended — same fonts, same glyphs, same metrics. Reality deviates sharply. Font substitution occurs when a computer system cannot access a specified font or a particular character within that font. The system then automatically replaces the missing font (or glyph) with another available one.

Understanding the "Font Substitution Will Occur" Warning: Causes and Solutions

When font substitution occurs, it can lead to several issues:
At its simplest level, font substitution is the process that occurs when a document using a particular set of fonts is displayed on a computer on which one or more of those fonts are not installed. The software carrying out the display—whether it's a web browser, a word processor, or a PDF viewer—substitutes a font that looks as similar as possible to the missing one.
