The alternate character patches come with the source code. You can find them inside the alt/ directory when you download the source from sourceforge. But if you are lazy to patch them yourself, then you can just download my archive, since the font I use is already a patched version.
You can see the difference between the character ‘a’ in the following two shots, for example. The first one is the default version and the second is the patched version.
I have uploaded the archive over at omploader. Just follow the link for the patched font.
