oddities with the bbold fonts

[Ralf Stubner <ralf.stubner@web.de>]

Hi everybody,

while comparing tetex and texlive packages in Debian we have found the
following oddities.

Both tetex and texlive contain:

support files and fonts for bbold:
* bbold.sty and Ubbold.fd in TEXMF/tex/latex/bbold
* sources and tfms in TEXMF/fonts/source/public/bbold and
  TEXMF/fonts/tfm/public/bbold

support files for sauter extension of bbold fonts:
* mathbbol.sty and ubbold.fd TEXMF/tex/latex/jknappen


Only tetex contains the needed font sources for the sauter extension of
bbold fonts in TEXMF/fonts/sources/jknappen/sauter.

Therefore simple files making use of these fonts fail on texlive:

\documentclass[a4paper,11pt]{article}
\usepackage{mathbbol}
\begin{document}
$\mathbb{R C}$
$\Eins$
\end{document}

I think the missing fonts can be found on CTAN:fonts/cm/sauter/addons/.
However, I am not sure if one should add these fonts or remove the LaTeX
support files from texlive.

In addition, I am wondering why this is working on tetex at all, given
that we have both ubbold.fd and Ubbold.fd. I allways thought that the
case for the encoding part in fd-files is optional.
