Is it a Unicode Font?

To determine if your font is Unicode-compliant, with all its characters coded and mapped correctly, choose the Font in any program (or in Font Book, set the preview area to Custom (Preview > Custom), and type Option-Shift-2.

If you get a euro character (a sort of uppercase C with two horizontal lines through its midsection), it's 99.9 percent certain the font is Unicode-compliant. If you get a graphic character that's gray rounded-rectangle frame with a euro character inside it, the font is definitely not Unicode-compliant. (The fact that the image has a euro sign in it is only coincidental: it's the image used for any missing currency sign.)

This assumes that you're using U.S. input keyboard, which is a little ironic when the euro symbol is the test. With the British keyboard, for instance, Option-2 produces the euro symbol if it's part of the font.

Security Update 2007-009 1.1 Released with Important Fixes

Send Article to a Friend

Shortly before the end of the year, Apple released Security Update 2007-009 to patch 41 vulnerabilities in Mac OS X 10.4.11 and 10.5.1. Many of these vulnerabilities can allow an attacker to take over your computer by simply sending you a malicious file or having you visit a malicious Web site. The affected applications and services include Address Book, CUPS (the printing service), and Quick Look.

(A few days after the initial Security Update 2007-009 was posted, Apple released version 1.1, which corrected a problem with Safari introduced in the prior update.)

Be aware that the Quick Look update will block any Quick Look plug-ins. We suspect this is a temporary fix and Apple will safely re-enable plug-ins in the (hopefully near) future.

A full listing of the updates can be found in Apple's security release notes. It's available through Software Update and in stand-alone form for Leopard (a 35.6 MB download) and Tiger (Universal) (a 27.4 MB download) or Tiger (PowerPC) (a 15.9 MB download).

This is an extremely important update fixing multiple critical vulnerabilities. You should apply this as soon as possible, since many of these are the kinds of vulnerabilities favored by Internet attackers.
