Bare Bones Software has released BBEdit 10.5.2, delivering fixes large and small for over 40 customer-reported issues. Among the highlights, the update now displays the name of each document as it’s opened in the “Restoring [BBEdit] state” panel, fixes a bug with Save a Copy that would result in data loss “if the wrong choices were made,” ensures that accurate results are returned in the pre-comparison screening for multi-file Find Differences, fixes BBEdit’s Search and Replace Automator action for grep-based searches, squashes a bug that would return stale Clipboard contents in operations that required a clipboard import from an external application, and stops BBEdit from beeping if you right-clicked in an improperly formed HTML or XML document. Note that BBEdit 10.5.2 now requires Mac OS X 10.6.8 Snow Leopard. ($49.99 new from Bare Bones or the Mac App Store, free update, $39.99 upgrade from pre-10 versions, 12.6 MB, release notes)
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.
