Collation Default Parameters

照合を指定すると、大文字・小文字やアクセント記号など、文字列を比較するための言語独自のルールを指定できます。

動作

一部の照合ロケールには、言語固有の特別なルールを使用するバリアントがあります。ロケールバリアントを指定するには、次の構文を使用します。

{ "locale" : "<locale code>@collation=<variant>" }

たとえば、中国語照合の unihan バリアントを使用するには、次のようにします。

{ "locale" : "zh@collation=unihan" }

See the collation page for a full description of collation behavior and syntax.

Collation Default Parameters

A collation document contains several optional parameters in addition to the required locale parameter. Depending on which locale you use, the default parameters may be different. See the collation page for a full description of collation syntax.

The following default parameters are consistent across all locales:

caseLevel : false
strength : 3
numericOrdering : false
maxVariable : punct

The following table shows the default collation parameters which may vary across different locales:
