正在检查文件/wp-admin/edit-tags.php, 我们看到它正在使用函数_ex() 转换字符串的步骤Description.

下列的_ex 路径，我们发现它最终使用了过滤器gettext_with_context 翻译文本。因此，有可能钩住它并修改所需的字符串。

以下代码是@toscho的简化版本Retranslate plugin. 请检查原始代码，以获得更通用的代码。

作为插件使用，或者只需将代码复制到主题的functions.php 文件<在这个例子中，我们有一个额外的上下文和替换
要解决OP问题，请从两个数组中删除第二个数组项

中的配置值$params_71992:

• context 如中所示/wp-admin/edit-tags.php
• replacements, 原始和所需翻译的字符串taxonomy, 分类名称，category, post_tags 或custom-taxonomy
