Using `font-name` is 'absolute', that is, it overrides any LilyPond
font switching mechanism.  This means that `\number` doesn't work.

There are two solutions: Either set up a font tree so that you can use
standard commands like `\bold` (and `\number`), or switch manually to
the `Emmentaler` font.  An example for the latter is

```
 \column \override #'(font-name . "Arial Bold")
 {
   D A \concat { F
\override #'(font-name . "Emmentaler-16") \small
                   ♯ } D A D
 }
```
