I have a problem with my (freshly updated) MiKTeX installation: I like to use `\mathbbold{1}` from the `bbold` package to obtain a blackboard bold 1. This works with TeX Live under Linux, but for font size 11 it does not work with MiKTeX. If I compile

```
\documentclass[11pt]{article}
\DeclareSymbolFont{bbold}{U}{bbold}{m}{n}
\DeclareSymbolFontAlphabet{\mathbbold}{bbold}
\newcommand{\ind}{\mathbbold{1}}
\begin{document}
$a$ \tracingall $\mathbbold{1}$
\end{document}

```

then in the log file I get the line

```
Missing character: There is no 1 in font bbold11!

```

and no blackboard bold 1 in the output. With TeX Live (and with font size 10) everything works as expected.

The problem seems to be that under TeX Live, `bbold/Ubbold.fd` is loaded, whereas under MiKTeX, `jknappen\ubbold.fd` is loaded. The former uses `bbold10.tfm`, the latter `bbold11.tfm`.

How can I solve this problem?
