For example, I'll often end up with a lot of documents with the same style of capital letters You could just look around for fonts with the same layout, size, weight, and style, and add them to the font folder, but it might take a bit of time to locate each font, and some might be too big to fit, so I prefer a few small font files to fill up the folder. You can find a bunch of fonts all in one place at Font Finder. It'll let you search for, search for, and sort by the size of the font. So, if you are having trouble getting the fonts that are normally available in the menu in InDesign on your webpages, and if you are creating PDFs, then you will want to make sure if the fonts that are typically available in InDesign are in the fonts' folder, and if they aren't, then you will need to activate and register those fonts. As you can see in the image above, the fonts are available in the font folder as well as the Font Finder. This means that you should be able to use them by just adding them to your font list in InDesign. You might need to re-create PDFs, but if you find one with missing pages at the top, or pages with a very small font, then you can probably create your own file.
