嵌入整个 ICU（full-icu）

此选项使生成的二进制链接与 ICU 静态地关联并包含全套 ICU 数据。 以这种方式创建的二进制文件没有进一步的外部依赖项并支持所有语言环境，但可能相当大。

This option makes the resulting binary link against ICU statically and include a full set of ICU data. A binary created this way has no further external dependencies and supports all locales, but might be rather large. See BUILDING.md on how to compile a binary using this mode.
