Hi,

Is sorting by Romanization, specifically Pinyin supported currently?

It should be sorted along other languages with Roman alphabet, so the sorting results should be in an order like this:

1. a,
2. b,
3. C, // ignore case
4. j,
5. jA,
6. Jb,
7. JC,
8. 姐 (Jiě), // consider the transliteration
9. s,
10. 石 (Shí),
11. x,
12. 小 (Xiǎo),
13. z

For now a normalizer with lowercase and asciifolding filters is used for the text keyword:

```auto
PUT test
{
  "settings": {
    "analysis": {
      "normalizer": {
        "my_normalizer": {
          "type": "custom",
          "char_filter": [],
          "filter": [
            "lowercase",
            "asciifolding"
          ]
        }
      }
    }
  },
  "mappings": {
    "properties": {
      "name": {
        "type": "text",
        "fields": {
          "keyword": {
            "type": "keyword",
            "normalizer": "my_normalizer",
            "ignore_above" : 256
          }
        }
      }
    }
  }
}

```

Thanks
