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°
  }
}
```
