`quotes`

Control the quotes.

Possible options:

"preferDouble": Use double quotes as possible. However if there're quotes or escaped characters in strings, quotes will be kept as-is.
"preferSingle": Use single quotes as possible. However if there're quotes or \ characters in strings, quotes will be kept as-is.
"forceDouble": Use double quotes. However if there're escaped characters in strings, quotes will be kept as-is.
"forceSingle": Use single quotes. However if there're \ char or " char in strings, quotes will be kept as-is.

Default option is "preferDouble". We recommend to use double quotes because behavior in single quoted scalars is counter-intuitive.
