Smile has updated PDFpen and PDFpenPro to version 6.0.2, dramatically reducing memory usage and adding an option to turn off Auto Save and Versions (found in the General pane of PDFpen’s preferences). The update brings several requested form-related changes, including improved tab ordering with automatic form creation, setting a multi-line property when automatically creating tall form fields, reverting to the default font when automatically creating form fields, and fixes for unspecified issues when saving PDF forms. Additionally, both editions fix issues with applying foreground, background, and stroke colors, and ensure that document permissions are respected when inserting page numbers. As of this writing, neither PDFpen nor PDFpenPro have been updated to version 6.0.2 in the Mac App Store. Upgrades from a previous major version of PDFpen or PDFpenPro cost $30 via Smile, but are free to those who purchased on or after 15 October 2012. If you want to upgrade to PDFpenPro from a previous version of PDFpen, the price is $40. ($59.95/$99.95 new with a 20-percent discount for TidBITS members, free update from version 6.0, 49.4/50.2 MB)
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.
