Hugo how to use " in printf

support
1

I use prebuild to create some markdown files.

now I want to render a shortcode in the file

{{ $content := "" }}

{{ range sort $book_list "Title" "asc" }} {{/* this is from json data */}}

{{/* 1. render Headlines */}}
{{ $content = printf "## %s\n\n" .Title  | printf "%s%s" $content | printf "%s" }}

{{/* 2. Render a Shortcode */}}
{{ $content = printf "{{< book title='%s' author='%s' isbn='%s'>}}\n\n"  .Title .Author .ISBN | printf "%s%s" $content | printf "%s" }}

{{ end }}

{{ $file = $content | resources.FromString "books/book-list.md" }}
{{ $output := $file.RelPermalink }}

So here I get in trouble because it renders nicely to:

## Camp concentration

{{< book title='Camp concentration' author='Thomas M. Disch' isbn='3453308009'>}}

but Hugo needs " " for the shortcode parameters to work

{{< book title="Camp concentration" author="Thomas M. Disch" isbn="3453308009">}}

How can I use printf " with="..." inside" ?
Normally I would use \" but that doesn’t work.

You can use string literals:

{{ printf `Hello "%s"` "world" }}
