Keeping a version of Helvetica
A few Mac OS X applications require an active version of Helvetica. The most common
symptom when Helvetica is missing is that the application does not display windows
or type does not display correctly. Corrupt fonts can also cause incorrect type display.
(See Appendix A, “Additional Resources,” for more information on this topic.)
If you regularly use any applications that require Helvetica: As soon as you remove
Helvetica from the system, be sure to install another version of Helvetica with your
font manager of choice. It doesn’t matter which font format you use—TrueType,
OpenType, or PostScript—as long as one version of Helvetica is present.
Removing or deactivating fonts on international systems
In addition to the fonts discussed previously that are required for any Mac OS X
system (Lucida Grande, Monaco, Keyboard, and LastResort), each international version
of Mac OS X requires specific fonts for proper operation.
You can determine which fonts are system fonts by looking in /System/Library/Fonts.
The fonts that must not be removed are listed below. They are also marked with a lock
icon when you view them with Font Book. Apple recommends that you leave all of
these fonts in place even if you do not plan to use all of the listed languages, because
you never know who might use your system or how it might be used in the future.
