The json-encoder in go escapes < > making it hard to read expressions

[sublibra]

The json-encoder used in corectl escapes common characters such as < > before sending this to the engine. It is correct json and engine handles this correctly and the presentation for the user mostly unescapes before sending back to the users. In some case it isn't and for reading purposes, especially in set expressions, this makes it really hard to read.

Consider changing the presentation of the json output to unescape the characters in following cases (may be more):

• unbuild output
• title, label etc in dim, measures

Example:

{
  "qInfo": {
    "qId": "dim-1",
    "qType": "dimension"
  },
  "qDim": {
    "qLabel": ">><< !#€%&/()=?",
    "qFieldDefs": ["({$<Type={'feature'}>} Size)"]
  },
  "qMetaDef": {
    "title": ">><< !#€%&/()=?"
  }
}

      "qApprMaxGlyphCount": 0,

unbuild output:

      ],
      "qFieldLabels": [],
      "qLabel": "\u003e\u003e\u003c\u003c !#€%\u0026/()=?"
    },
    "qMetaDef": {
      "title": "\u003e\u003e\u003c\u003c !#€%\u0026/()=?"
    }
  }

Can be set on the encoder, but then we need reuse the encoder across all commands.

This is bug is due to enigma-go, not a corectl. The data on our part in the above example is:

{
  "qInfo": {
    "qId": "dim-1",
    "qType": "dimension"
  },
  "qDim": {
    "qLabel": ">><< !#€%&/()=?",
    "qFieldDefs": [
      "({$<Type={'feature'}>} Size)"
    ]
  },
  "qMetaDef": {
    "title": ">><< !#€%&/()=?"
  }
}

This data is sent using enigma which escapes the characters.
I'll keep this issue open until it is fixed in enigma.
