Support custom quote characters?

[kevinushey]

Would it be possible to customize the quote character used when generating YAML? For example:

> yaml::as.yaml(as.character(Sys.Date()))
[1] "'2022-04-14'\n"

I'd like a way to tell yaml to quote fields using double quotes here, but only if quotation is required.

One can set the "quoted" attribute to force the use of double quotes, but then those quotes are applied on all string values, even those which might not require them.

It's an interesting idea, but would be complicated to implement.
