从记事本中检索保存为ANSI文本文件的unicode文本 [英] retrieving unicode text from notepad which is saved as ANSI text file

问题描述

昨天我在记事本文件中写了一些文本，该文件中有很多Unicode字符，并将文件保存为ANSI。记事本给了我一些警告，我单击确定，没有完全阅读它和关闭记事本。

Yesterday I wrote some text in a notepad file which was full of Unicode characters and saved the file as ANSI. Notepad gave me some warning, which i clicked OK without reading it fully and closed notepad.

今天，当我再次打开相同的文本在记事本，我看到记事本充满???标志。我现在明白这是因为我将Unicode数据保存为ANSI文本。有没有办法检索这个文本？可能使用一些十六进制编辑器等等？

Today when I again opened the same text in notepad, I am seeing notepad full of ??? signs. I now understand that this happened because I saved Unicode data as ANSI text. Is there a way to retrieve this text back? May be using some hex-editor or so?

推荐答案

否。某些字符无法编码在某些编码中。例如，风不能在ISO-8859或任何其他单字节编码中进行编码。每个ANSI编码也只能编码所有可能字符的某个子集。根本不可能存储未在该编码中的特定ANSI编码中定义的字符，它们根本不在那里定义。

No. Certain characters cannot be encoded in certain encodings. "風" cannot be encoded at all in ISO-8859 or any other single-byte encoding, for example. Each ANSI encoding also can only encode a certain subset of all possible characters. It is simply not possible to store characters not defined in a particular ANSI encoding in that encoding, they're simply not defined there.

所以，他们走了。你最好拿出一个备份。

So, they're gone. You better pull out a backup.
