    escaped. The following characters will be converted to their
    corresponding character entities:

        & < > " ' / `

    This implementation is based on the [OWASP HTML escaping
    recommendations][1]. In addition to the characters in the OWASP
    recommendations, we also escape the <code>&#x60;</code> character, since IE
    interprets it as an attribute delimiter.

    If _string_ is not already a string, it will be coerced to a string.
