Further to my earlier post on discovering a bug with DfontSplitter for Windows which surfaces on some versions of Windows, I have now discovered a workaround for this issue on Vista.

If you are using DfontSplitter on Vista and when you convert a font, Windows then complains that it is not a valid font file, you can use this workaround to install the font into your Fonts folder. The font should then work normally.

I’ve tested this with a bunch of fonts, but it might not work absolutely everywhere. You’ll just have to try it and see if it helps.

The details of the workaround are listed here, on the dev wiki.

I’m still interested in testers for XP Service Pack 2. If you’d like to help out please get in contact via email or leave a comment below.

I have had a bug in DfontSplitter for Windows reported to me, which I have been able to confirm. On at least the following systems, the resulting TTF files that the program converts are reported as corrupted by Windows:

• Windows XP Professional SP3
• Windows Vista Business SP1

On my original development system, which was Windows XP Gold (unpatched – and also not connected to the internet), I had no problems.

This issue does not affect the Mac version of the software.

I am looking for anyone with access to Windows XP SP2 (or SP1, or XP Gold) to see if the problem is present there and hopefully from there I can work out if anything can be done, or how to potentially resolve it.

If you can help me out and you run or can run on one of these systems, please let me know by commenting below or email me.

For the time being, I can’t be sure which versions of Windows DfontSplitter will run on correctly. Sorry if you did download it and it didn’t work. 🙁

Yeah, so, I just released some Windows software.

My program for converting and splitting Mac OS X .dfont files into TTF files, DfontSplitter has been a pretty popular route in to my website for some time now.

While the original program is written for OS X, it became apparent from my website statistics that many people who needed to convert .dfont to .ttf were Windows users.

So, today, I have released DfontSplitter for Windows, version 0.1. This program is, again, simply a wrapper script for fondu, which does the real work. It has a completely unique GUI, custom built for the Windows platform.

There is also a brand new project page for DfontSplitter, with links to both the Mac and Windows versions of the software and the documentation too.

Hopefully this can serve the need of Windows users who need to convert those filetypes, and don’t want expensive or spyware-ridden software. Enjoy!

A quick footnote – this is a bit of a licensing quagmire. There are lots of different licenses that apply to different bits of DfontSplitter for Windows, including GPL 3.0, GPL 2.0, BSD and Creative Commons. That’s all explained on the project page, and in further depth in readme and licence files in the downloads.

Oh and it’s also slightly ugly, in terms of how it interacts with fondu. But it works. 🙂
