Title: Fix coding tag.

I think this works with Python, where `utf8` is an alias for `utf-8`, but it emacs doesn't like it, giving the warning:

```
Warning (mule): Invalid coding system `utf8' is specified
for the current buffer/file by the :coding tag.
It is highly recommended to fix it before writing to a file.
```
