打印大于0x7f的ASCII字符 [英] printing ASCII character greater than 0x7f
问题描述
我在我的项目中遇到过一种情况，我在这里阅读了一个带有
的文本文件，其中一些字符大于十六进制0x7f。
i需要写字符（0xE0）将新文件作为例外。然而，当我想要通过Console.Write来写这个时候。或filestream.Write或似乎价值变化了。
。大多数输出文件都处于文本模式。
如果我以二进制模式查看原始文件，我会看到我有这个角色的问题
问题作为e0 00但当我重写它时，我得到C3 A0。
我无法在输出文件中重现读取信息。有没有
这样做的方法，如果是这样的话？
i have come across a situation in my project where i read a text file with
some characters greater than hex 0x7f.
i need to write character (0xE0) to a new file as an exception. however when
i attempt to write this via "Console.Write" or "filestream.Write" it seems
the value changes. most of the output file is in text mode.
if i view the original file in binary mode i see the character i''m having
issue with as "e0 00" but when i re-write it i get "C3 A0".
i just can not reproduce the read information in my output file. is there
way to do this and if so how?
推荐答案
嗯，ASCII没有定义任何字符在此之上。你需要知道
文件的代码页，并使用正确的编码 - 通过（对于
示例）Encoding.GetEncoding（int codepage）[并将此编码传递给
您正在使用的StreamReader等。
否则，将进行翻译。而且他们是否代表您的原始数据是否是任何人的猜测。

Well, ASCII doesn''t define any characters above this. You need to know
the codepage of the file, and use the correct encoding - via (for
example) Encoding.GetEncoding(int codepage) [and pass this encoding into
whichever StreamReader etc you are using].
Otherwise, translations will occur. And whether they represent your
original data is anyone''s guess.

有没有找到代码页？是否有一个很好的参考资料来源？

is there away to find the codepage? is there a good reference source?

确定文件的代码页没有硬性规则。
单个文件（即一个字节序列） ）对于几个不同的代码页，可能有效（但
不同的含义）。

There''s no hard and fast rule for determining the codepage of a file.
A single file (i.e. a sequence of bytes) may be valid (but with
different meanings) for several different codepages.
