echo Windows批次中的UTF-8个字符

Question

Can I use echo to generate an UTF-8 text file? For example if I want to generate a file that contains the character ę :

echo "abcd ę" > out.txt

(the batch file is encoded with UTF-8)

the result is an ANSI encoded file and the ę character is transformed into ê . How can I convince echo to generate an UTF-8 file?

If it's not possible, then can I change the encoding of the text file after creating it? Is there any tool in the gnuwin32 package that can help me to change the encoding?

thanks

Answer 1

使用chcp命令将 utf-8 的活动代码页更改为 65001。

chcp 65001

Answer 2

尝试使用 /U 开关启动 CMD.exe：它会导致所有管道输出为 Unicode 而不是 ANSI。

Answer 3

chcp 65001

as mention by @cuixiping is a good answer but it require to change cmd default font to Lucida Console for example, as you can read here: https://superuser.com/questions/237081/whats-the-code-page-of-utf-8#272184

and of course, as mentioned by @BearCode, the text should be in utf-8… in my case, with Vim under GNU/Linux with remote access, but notepad++ is right way too!

Answer 4

The problem was that the file contained the line:

<META content="text/html; charset=iso-8859-2" http-equiv=Content-Type> 

and then Notepad2 and Firefox was changing the charset, showing Ä instead of ę. In plain Notepad, the file looks ok. The solution was to add the UTF-8 signature (Byte Order Mark) at the beginning of the file:

echo1 -ne \xEF\xBB\xBF > out.htm

(echo1 is from gnuwin32)

thanks for the answers

Answer 5

Appears as well as changing the code page you need to write at least one unicode character in your first echo out to the file for the file to be saved as unicode. So your batch file itself needs to be stored in a unicode format like UTF-8.

Answer 6

I'm not sure if this is the answer you are looking for or if it's already been answered for you... 
I'd use the catet character ( ^ ) in a batch file and output to a file using escape character ^. See examples..
Desired output...
<META content="text/html; charset=iso-8859-2" http-equiv=Content-Type> 

Replace code with this: 
Example 1: echo ^<META content="text/html; charset=iso-8859-2" http-equiv=Content-Type^> 
Example 2: echo ^<?xml version="1.0" encoding="utf-8" ?^>
