Пis Unicode character 0x041F, and its UTF-8 encoding is 0xD0 0x9Fresulting in D?.
П是 Unicode 字符0x041F，其 UTF-8 编码0xD0 0x9F导致D?.
Since the function only returns the input parameter, as commenters already discussed, I conclude that your original input string is actually in UTF-8, and you want to convert it into native .Net string.
由于该函数只返回输入参数，正如评论者已经讨论过的，我得出结论，您的原始输入字符串实际上是 UTF-8，并且您希望将其转换为原生 .Net 字符串。
Where does the original string come from?
原始字符串来自哪里？
Instead of reading the input into a C# string, change your code to read a byte[], and then call Encoding.UTF8.GetString(inputUtf8ByteArray).
不要将输入读取到 C# 中string，而是将代码更改为读取byte[]，然后调用Encoding.UTF8.GetString(inputUtf8ByteArray).

I Tried the following code below and these were my results:
我尝试了下面的代码，这些是我的结果：
string test="Привет";
byte[] utf8Bytes = Encoding.UTF8.GetBytes(test);
String str1 = Encoding.Unicode.GetString(utf8Bytes);
String str2 = Encoding.UTF8.GetString(utf8Bytes);
Output of str1=?胑???苑
str1=?胑???苑的输出
Output of str2=Привет
str2=Привет 的输出
