The JSON implementation in Open vSwitch has the +following limitations: + + - Null bytes (\u0000) are not allowed in strings. + + - Only UTF-8 encoding is supported. (RFC 4627 also mentions + UTF-16BE, UTF-16LE, and UTF-32.) + + - RFC 4627 says that names within a JSON object should be unique. + The Open vSwitch JSON parser discards all but the last value + for a name that is specified more than once. + The descriptions below use the following shorthand notations for JSON values. Additional notation is presented later.
