  +==== Normalize full-width characters
  +
  +The `kuromoji_tokenizer` tokenizer uses characters from the MeCab-IPADIC
  +dictionary to split text into tokens. The dictionary includes some full-width
  +characters, such as `ｏ` and `ｆ`. If a text contains full-width characters,
  +the tokenizer can produce unexpected tokens.
  +
  +For example, the `kuromoji_tokenizer` tokenizer converts the text
  +`Ｃｕｌｔｕｒｅ　ｏｆ　Ｊａｐａｎ` to the tokens `[ culture, o, f, japan ]` by
  +default. However, a user may expect the tokenizer to instead produce 
  +`[ culture, of, japan ]`.
  +
  +To avoid this, add the <<analysis-icu-normalization-charfilter,`icu_normalizer`
  +character filter>> to a custom analyzer based on the `kuromoji` analyzer. The
  +`icu_normalizer` character filter converts full-width characters to their normal
  +equivalents.
  +
  +First, duplicate the `kuromoji` analyzer to create the basis for a custom
  +analyzer. Then add the `icu_normalizer` character filter to the custom analyzer.
  +For example:

  +            "filter": [
  +              "kuromoji_baseform",

  +              "ja_stop",
  +              "kuromoji_stemmer",
  +              "lowercase"
  +            ]
  +          }
  +        }
  +      }
  +    }
  +  }
  +}
  +----

  +analyzer.
  +<2> Adds the `icu_normalizer` character filter to the analyzer.
