~~Behavior~~行为
~~Supported Languages and Locales~~支持的语言和地区
~~Collation Default Parameters~~排序规则默认参数

~~Collation~~排序规则 ~~allows users to specify language-specific rules for string comparison, such as rules for lettercase and accent marks.~~允许用户为字符串比较指定特定于语言的规则，例如字母大小写和重音符号的规则。

Behavior行为

~~Some collation locales have variants, which employ special language-specific rules.~~ 一些排序规则区域设置有变体，它们使用特定于语言的特殊规则。~~To specify a locale variant, use the following syntax:~~要指定区域设置变量，请使用以下语法：

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

~~For example, to use the unihan variant of the Chinese collation:~~例如，要使用中文排序规则的unihan变体：

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

~~See the collation page for a full description of collation behavior and syntax.~~有关排序规则行为和语法的完整描述，请参阅排序规则页面。

Collation Default Parameters排序规则默认参数

~~A collation document contains several optional parameters in addition to the required locale parameter.~~ 除了必需的locale参数外，排序规则文档还包含几个可选参数。~~Depending on which locale you use, the default parameters may be different.~~ 根据您使用的locale，默认参数可能会有所不同。~~See the collation page for a full description of collation syntax.~~有关排序规则语法的完整描述，请参阅排序规则页面。

~~The following default parameters are consistent across all locales:~~以下默认参数在所有地区都是一致的：

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

~~The following table shows the default collation parameters which may vary across different locales:~~下表显示了默认排序规则参数，这些参数在不同的地区可能有所不同：
