C＃中的文本编码问题 - encoding.getchars（）会产生奇怪的结果 [英] Text encoding problem in C# - encoding.getchars() yields weird results

问题描述

我正在开发一个涉及用Shift-JIS编码的日文文本的项目。我正在尝试从字节数组中解码有用的字符，如下所示：

I'm working on a project that involves Japanese text encoded in Shift-JIS. I'm trying to decode useful characters from arrays of bytes like so:

Encoding encoding = Encoding.GetEncoding(932);
string test = new string(encoding.GetChars(byteArray));

这适用于99％的数据，但我得到了奇怪的结果少数几个人物。例如，字符'¨'。如果我获得对应于该字符的字节，如下所示：

This works for 99% of the data but I'm getting weird results for just a handful of characters. The character '¨', for example. If I obtain the bytes corresponding to that character like this:

byte[] getBytesTest = encoding.GetBytes("¨");

结果正是我所期望的。两个字节，0x81和0x4E，这是该字符应该在Shift-JIS中。

如果我尝试将其转换回字符串，但是：

The results are exactly what I expect. Two bytes, 0x81 and 0x4E, which is what that character is supposed to be in Shift-JIS.
If I try to convert it back to a string, though:

string getCharsTest = new string(encoding.GetChars(getBytesTest));

...我得到默认错误输出？。



所以tl; dr，我正在试图找出原因：

...I get the default error output "?".

So tl;dr, I'm trying to figure out why this:

byte[] getBytesTest = encoding.GetBytes("¨");
string getCharsTest = new string(encoding.GetChars(getBytesTest));

产生？结果而不是¨。



我尝试过：



将GetBytes（）的结果传递给GetChars（）并手动传递字节，如下所示：

yields "?" instead of "¨" as a result.

What I have tried:

Passing the results of GetBytes() to GetChars() and manually passing the bytes in like this:

encoding.GetChars(new byte[] {0x81, 0x4E})

都未能产生预期的结果。



不知道该去哪里。

both fail to produce the expected result.

Not sure where to go with this.

推荐答案

你的代码还可以，当我在VS2017的Win 10上试一试时，它可以工作：

Your code is ok, when I try this on Win 10 in VS2017, it works:

System.Text.Encoding encoding = System.Text.Encoding.GetEncoding(932);
byte[] getBytesTest = encoding.GetBytes("¨");
string getCharsTest = new string(encoding.GetChars(getBytesTest));

也许你需要更新你的Windows？

Maybe you need to update your Windows ?

这里的问题是编码哪个控制台无法理解。如果您将文件写入文件而不是控制台，您将获得预期的文本。

Problem here is encoding which console doesn't understands. If you will write the content in file instead of console, you'll get the text as expected.

File.WriteAllText("file.txt", getCharsTest);
