The situation is familiar: you or someone else uses a non-standard font (not a PowerPoint safe font) in your presentation. You then open this same presentation on another computer, and PowerPoint uses another font to display the same text. Why does it do so? The reason is simple enough: the font originally used is not available on the other system. The end user has no idea that PowerPoint substituted one font with another. There is no information provided at all. The font that is used as a substitute cannot be identified. If you have 500 fonts on your system, there’s no way to understand why PowerPoint used a certain font as a substitute.
