LilyPond's input encoding is UTF-8; markup strings must be thus
emitted as UTF-8, too. Its Texinfo documentation extracts code
snippets from master files (using the `lilypond-book` script),
compiles them for graphical output, and shows the source code at the
same time. Example:
```
\markup {
default
\hspace #2
\rotate #45
\line {
rotated 45°
}
}
```
