I’ve been busy beavering away in Xcode and I am now proud to release version 0.3 of DfontSplitter for Mac.

So, here are the release notes:

New Features and Bugfixes

• Now supports the splitting and extracting of TrueType Collection (TTC) files in addition to traditional Mac Datafork (dfont) files.
• The conversion of a .dfont will no longer fail if there is already a TTF of the same name in the same directory; it will now overwrite the existing file.
• Users of Snow Leopard on Intel Core 2 and Xeon Macs will now be running the DfontSplitter application in 64-bit mode.
• Improved error message text.

Known Issues

• Converting TTC files on Mac OS X Leopard (10.5) does sometimes run into problems, where the TTC splitting script can’t open the TTC file. The reason for this is currently unclear.
• Moving TTF files that have been extracted from a .dfont over to Windows — please see this workaround.

As always, go across to the DfontSplitter project page to download the new release.

If you’re already using DfontSplitter for Mac, simply go to DfontSplitter > Check for Updates within the application to upgrade to the new release.

UPDATE 2011-05-09: While some particularly stubborn fonts do require this process, users who have previously experienced difficulty with older versions of DfontSplitter should first try with DfontSplitter 0.3.1 or later, which include a possible fix for this issue.

I think I’ve finally found a solution to this annoying error message that Windows gives when you use DfontSplitter to convert some fonts and then try and use those converted fonts in Windows.

It involves using a third-party open source application called FontForge to convert the TTFs that DfontSplitter gives you from a Mac-specific TTF format into ‘regular’ TTF format.

A full tutorial on using this method is included as a YouTube video screencast below.

If you can’t or don’t want to watch the video, essentially the process is:

• Use DfontSplitter on the .dfont file as normal
• Open the resulting TTF files you want in FontForge
• Export each TTF file from FontForge with File > Generate Fonts. Make sure TrueType format is selected.
• Import the resulting TTF files into Windows fonts folder.

Please do let me know if this process works for you and give any feedback — especially if you’d previously had problems using a .dfont you had wanted to use on Windows.
