multiple error messages re: corrupt $C font

by ludicmichael / November 8, 2009 3:05 AM PST

I have an intel Macbook and a PPC iMac both running latest version Tiger. First the iMac then the laptop developed multiple (one on top of the other messages warning that there was an error detected with the $C font. It suggested I should quit all apps and try to remove the font. I think this happened in Mail on both machines. What should I do? Is it a piece of malware? Strange that it should happen on both machines.

Thanks for any help out there

Font Book
by mrmacfixit Forum moderator / November 8, 2009 4:29 AM PST

Launch Font Book from the Applications menu, select all the Fonts and from the menu bar, select Validate Font.

This will run a check on all the fonts and advise you if there are any that could be causing a problem.

You can then delete the offending font.

As both machines got the same error, from the Mail, it is probably just a problem in one of the emails you received.

font error

I did as you suggested but there were apparently no bad fonts. After I had the problem I re-started both machines after trashing as many e-mails as I could and I've not had a problem since. At least I know what to do if it happens again.

Thanks again.

Hint about source of problem
by fgfletcher / November 4, 2016 11:08 AM PDT

Found a hint about where the issue is arising:

Using Safari 4.1.3 under Mac OS X 10.4.11 on Mac G5

Error "Problem detected with the font - in the font file $C."
and display is filled with boxed "A"s

Error only occurs if
in Safari Preferences
Security pane
"Enable JavaScript" is checked.

UNchecking it, closing the Preferences window and reloading the web page
results in normal type.
