« Reliably Changing Versions of Fonts

For people who design fonts, swapping versions of your font can be a problem, as your operating system or apps have font caches which may become confused when you replace your fonts on the fly. The app you are using a font in may sometimes still display/​use the old version, even though you replaced it! So for people who need to be absolutely sure they are getting the new version, here are some options. Note that latest versions of Adobe CC apps may recognize fonts swapped on the fly. Office 360 as well, at least on Windows. So if you are not having trouble, and you are swapping fonts some other way, good for you! But if you are having trouble, here are some more options.

Here are some approaches for reliably swapping versions of fonts that have the same internal names, to new versions. This applies to both Mac and Windows, and across all apps as well. When working this way, as best as I recall, in the past 10–15 years, I have only hit font caching problems once! I suspect that was just a failure to apply my method religiously enough. There are two options for fonts with the same internal names on the desktop, plus to avoid the problem entirely, there is an approach to making font names unique, and some links to web-​based test sites.

Option 1: Brute force (cross-​platform)

1. Close apps that you are using the fonts in, particularly those which cache your fonts, including Adobe CC apps and Microsoft Office.
2. Then, uninstall the “old” font version from your OS. Don’t just overwrite it in place with the new version! (If you are using a font management app, you can just deactivate, but I usually nuke them anyway, I don’t need 170 versions of the same font kicking around.)
3. Relaunch those darn font-​caching apps, including Adobe CC apps and Microsoft Office. That’s after you uninstall the font. Even open a doc that uses the now-​missing font! This gives the app and its cache a chance to recognize the font is no longer there and update appropriately.
4. Quit Office apps (without saving your docs, no need). Note: no need to quit Adobe CC apps, they can recognize newly-​installed fonts on the fly.
5. Install your new font versions; or activate them in your font manager.
6. If you are using Office apps with your fonts, you can launch them apps again and work normally.

Option 2: FontNuke (Mac only)

I forgot about this option for a while, but was reminded of it by James Montalbano in a thread on TypeDrawers. FontNuke is a Mac utility that clears font caches, and then reboots your system. It’s available through major utility aggregators like MacUpdate and CNet. I’ve used it occasionally, and it works fabulously. Downside: it requires a system restart. That’s why I ended up tending to go with Option 1. (Also, Mac restarts used to take longer than they do nowadays. Yay for SSDs!) Upside: if your system font caches have gotten messed up, or you don’t want to go through all the steps above, it becomes the simplest solution.

Option 3: Font Naming Tricks (cross-​platform)

Option 1 seem like too much freakin’ work? Or you need something that works on Windows, or reboots suck? I hear you. That’s why as a font designer, I sometimes work with a system where instead of keeping the internal names the same, I actually put the build version number right at the end of the gosh-​darned family name, so it shows in the menu with the version number. I also put it on the end of the file name. I leave it this way as long as possible during development. Sure, this has its limitations, as the new font won’t just automatically substitute for the old one in existing documents. And it has to be changed before releasing the font. But if I am in the midst of frequent font revisions, it also means I can swap out font versions constantly, as often as I like, and not worry in the least about my apps or OS getting confused. That is pretty sweet.

1. Before generating the actual TTF or OTF font, increment a build number at the end of the font family name
2. Remember that your existing docs won’t recognize this as being the same font family.  🙁  But you don’t have to worry about caching and conflicts! 🙂

Option 4: Test in the browser instead

If you don’t have to test in a desktop app, you can avoid a lot of grief! There are sites for testing fonts in a web browser. You can drag the font into a browser window and test it there. Impallari’s is great

• WebFont|Test

If you are doing browser-​based font testing—or font testing anywhere, really—with an incomplete character set, consider Miguel Sousa’s Adhesion Text to get useful words for test purposes. (Don’t miss the options for other languages, and more!)
