Problem

Pandoc conversion from either Markdown or Org Mode to EPUB fails when using a YAML metadata file containing an ampersand in the title, even when the title value is quoted.

I have not found this error in open/closed issues or PRs or discussed on the wiki

commands run to reproduce

pandoc -f markdown -t epub --epub-metadata=metadata.yaml > simple.epub simple.md
pandoc -f org -t epub --epub-metadata=metadata.yaml > simple.epub simple.org

Pandoc error in both cases

Invalid XML in epub metadata:
ParseError {errorContexts = ["text content"], errorMessage = "Failed reading: parseTextContent", errorPosition = 4:48 (82)}

--epub-metadata takes a special kind of XML file, not a YAML file.
If you want to use YAML metadata this way, you can use --metadata-file.

From the docs:

--epub-metadata=FILE

Look in the specified XML file for metadata for the EPUB. The file should contain a series of Dublin Core elements. For example:

 <dc:rights>Creative Commons</dc:rights>
 <dc:language>es-AR</dc:language>
