These help dvipdfm for text extraction / searching in pdf.

The names are funny (in fact most bytes of the filename come from some
md5sum of the encoding file itself), because I did not know any better
names. I have extracted the encoding from the pfb files of the bsr fonts
and grouped fonts with identical encoding together.

I have taken the encoding of the pfb file which is the same as Knuth's

For non-text fonts, it does not really matter...

Sebastian does not only want to provide a useful TeX system, but he also
wants to provide a collection of free software which gives some minimum
level of freedom to the users. The utopia fonts must not be changed,
so you can't fix a bug in it or add some accents that you need.

Sure, the "free software" decision means to omit some stuff. On the other
hand, that decision has helped the whole license issue in the TeX world
a lot.
