    Description

      I have field first_letter of type ICUCollationField and I do group query like so:

      q=:&group=true&group.field=first_letter&fl=first_letter&sort=first_letter+asc

      And get smth like this:

      "grouped": {
    "first_letter": {
      "matches": 138,
      "groups": [
        {
          "groupValue": ")\u0000",
          "doclist": {
            "numFound": 3,
            "start": 0,
            "docs": [
              {
                "first_letter": "A"
              }
            ]
          }
        },
        {
          "groupValue": "+\u0000",
          "doclist": {
            "numFound": 27,
            "start": 0,
            "docs": [
              {
                "first_letter": "B"
              }
            ]
          }
        },
        ........

      Letters are obviously stored as they shoud be, and sorting works fine.
