chcp 65001和一个.bat文件

问题描述

我在Windows shell中的chcp 65001命令有问题.

I have a problem with chcp 65001 command in Windows shell.

我需要在文件夹中生成文件列表.所以我运行了cmd.exe，输入了

I need to generate a list of files in a folder.So I ran cmd.exe, typed

cd folder
dir /B /O:N > list_of_files.txt

它有效，但是我在某些文件名中使用特殊的非ASCII字符时遇到了问题.所以我加了chcp 65001

It worked, but I had a problem with special, non-ASCII characters which are in some file names.So I addedchcp 65001

一切正常，但是当我将这些命令放入.bat文件时，该脚本不起作用.

Everything worked, but when I put these commands into a .bat file, the script doesn't work.

所以

cd folder
chcp 65001
dir /B /O:N > list_of_files.txt

不会生成列表.

和

cd folder
chcp 65001 && dir /B /O:N > list_of_files.txt

以及

cd folder
chcp 65001 > nul && dir /B /O:N > list_of_files.txt

生成列表，但使用默认编码:/.

generates the list, but with the default encoding :/.

所有内容都可以在cmd.exe中使用，但不能在.bat文件中使用.

Everything works in cmd.exe, but not in .bat files.

我已经阅读了以下主题:stackoverflow.com/问题2182568/batch-script-is-not-exected-if-chcp-被调用，但没有帮助.

I've read the topic: stackoverflow.com/questions/2182568/batch-script-is-not-executed-if-chcp-was-called, but it didn't help.

我部分解决了我的问题，将chcp 65001更改为chcp 1250，因为所有字符都在此编码中.但这实际上并不能解决问题.

I partially solved my problem, changing chcp 65001 to chcp 1250 because all characters were in this encoding. But actually this doesn't answer the question.

推荐答案

使用cmd /U.参见 http://ss64.com/nt/cmd.html :

• /A输出ANSI字符
• /U输出UNICODE字符(UCS-2小端)

• /A Output ANSI characters
• /U Output UNICODE characters (UCS-2 Little Endian)

这是我的尝试(当然，在cmd /A下启动):

Here's my attempt (launch it under cmd /A, of course):

@ECHO OFF >NUL
SETLOCAL EnableExtensions

:: create a UNICODE file with Byte Order Mark using `wmic`
chcp 852 >NUL
>list_of_files.txt wmic os get localdatetime

:: store a line with BOM to a variable
:: although FINDSTR does not support UTF-16 files
:: it will read first three bytes at least
for /F "delims=" %%G in ('
    findstr "^" list_of_files.txt
  ') do set "UTF8BOM=%%G"

:: write BOM only* to a file (* echo writes hexadecimal value FFFE0D0A)
:: the `<NUL set /p =text` trick does not work: chokes down leading `FF`
>list_of_files.txt echo(%UTF8BOM:~0,2%

chcp 65001 >NUL
:: add CRLF in  Unicode (hexadecimal 0D000A00)
>>list_of_files.txt cmd /U /C echo(

:: add result of `dir /B /O:N` in Unicode
>>list_of_files.txt cmd /U /C dir /B /O:N

:: check the result: still invalid first line, see output
type list_of_files.txt
chcp 852 >NUL

输出.仍然无效的第一行(该十六进制0D0A)，抱歉；使用另一种方法获取 pure Utf-8字节顺序标记:

Output. Still invalid first line (that hexadecimal 0D0A), sorry; use another method to get pure Utf-8 byte order mark:

==>cmd /A /C D:\bat\SO\UTF8BOM32182619.bat
਍
cpANSI_OoCcSsUu.txt
cpANSI_ÖöÇ窺Üü.txt
escrzyaie.txt
ěščřžýáíé.txt
list_of_files.txt
