如何使用「随机国家生成器」？How do I use the Random Country Generator tool?
在「随机国家生成器」中，按需设置「范围」、「大洲」、「数量」等选项，然后点击「随机抽取」、「复制名称」按钮即可。In the Random Country Generator: Set "Pool", "Continent", "Count", then click "Pick", "Copy names".
数据来源是什么？Where does the data come from?
国家列表、大洲、首都和联合国会员身份来自开源数据集 mledoze/countries（ODbL 许可），使用 2026 年 10 月 18 日从 GitHub 主分支下载的数据（最新正式版为 5.1.0，2025 年 2 月发布），共 250 个国家和地区。中文名称采用 Unicode CLDR 48 的简体中文地区名称（cldr-json 48.2.3，2026 年 10 月 18 日逐一核对），只有香港、澳门、台湾例外：CLDR 写作“中国香港特别行政区”“中国澳门特别行政区”“台湾”，本工具显示为“中国香港”“中国澳门”“中国台湾”。联合国会员国按 193 个会员国计算，梵蒂冈（教廷）和巴勒斯坦是观察员国，只在“全部国家和地区”中出现。“南极洲”一类包括南极洲和布韦岛、赫德岛等 5 个南极地区，它们都不是联合国会员国。更改范围、大洲或“不重复”会立即重新抽取。The list, continents, capitals and UN membership come from the open mledoze/countries dataset (ODbL licence), downloaded from its GitHub main branch on 18 Oct 2026 (latest tagged release: 5.1.0, February 2025), 250 countries and territories in all. Chinese names are the Simplified Chinese territory names from Unicode CLDR 48 (cldr-json 48.2.3, each checked on 18 Oct 2026). The only exceptions are Hong Kong, Macao and Taiwan. CLDR calls them the Hong Kong SAR of China, the Macao SAR of China and Taiwan; in Chinese mode this tool shows them prefixed with the word for China (as in 'China Hong Kong'). UN membership counts the 193 member states; the Holy See (Vatican) and Palestine are observer states and appear only under All countries and territories. The Antarctica option covers Antarctica and 4 other Antarctic territories such as Bouvet Island and Heard Island, none of which are UN members. Changing the pool, continent or No repeats draws again straight away.
抽取是公平随机的吗？Is the draw fair?
使用浏览器的 crypto.getRandomValues 和拒绝采样，范围内每个国家被抽中的概率完全相同；勾选“不重复”时，同一次抽取不会出现重复。It uses crypto.getRandomValues with rejection sampling, so every country in the pool is equally likely. With No repeats ticked, a single draw never repeats a country.
国旗为什么显示成两个字母？Why does a flag show as two letters?
国旗使用 Unicode 区域指示符号组成的 emoji。Windows 系统自带字体不显示国旗 emoji，会显示为两个字母（如 CN），这是系统限制，名称和数据不受影响。Flags are emoji built from Unicode regional indicator symbols. Windows' built-in fonts do not draw flag emoji, so you see two letters (such as CN) instead. This is a system limitation; names and data are unaffected.
随机结果真的随机吗？Is the randomness truly random?
「随机国家生成器」使用浏览器的 crypto.getRandomValues（密码学安全随机数）生成结果，并做了无偏处理，每个结果出现的概率相同。The Random Country Generator uses crypto.getRandomValues (cryptographically secure randomness) with unbiased sampling, so every outcome is equally likely.
