c++ - 从 Unicode 代码点获取字符 - C++

Question

我有两个问题。

1 - 我获得了 Unicode 代码点，我如何获得与该代码点关联的字符？像这样的东西:

int code_point = 0xD24;
char* chr = (char*) code_point;

但上面的代码因抛出异常而失败。

2 - 假设代码点存储在文件中，我将代码点读取为字符串，如何将其转换为有效的 Unicode 字符串？

我正在寻找独立于平台的解决方案。任何帮助都会很棒!

你看过International Components for Unicode了吗？项目？根据网站，

ICU is a mature, widely used set of C/C++ and Java libraries providing Unicode and Globalization support for software applications. ICU is widely portable and gives applications the same results on all platforms and between C/C++ and Java software.
