Enclosing quotes in the YAML files for training data examples with entities

I have a question regarding the usage of enclosing quotes in YAML files when working with training data examples with entities. According to the YAML documentation, we need to use quotes to separate scalars when a comma or square bracket is present inside the scalar, as these characters can end the plain scalar. (In this case, one scalar is one example). Documentation - Quoting - Learn - yaml.info Considering this, should we enclose examples with entities (which have square brackets) in quotes when defining them in YAML files?
