How would I specify this code block
```{r, engine = "tikz", engine.opts=list(dvisvgm.opts = "--font-format=woff")}
```
using YAML syntax instead of R syntax? Something along the lines of:
```{r}
#| engine: tikz
#| engine.opts: ???
```
Try
#| engine: tikz
#| engine.opts:
#| dvisvgm.opts: "--font-format=woff"
