w10系统txt默认文件编码utf-8怎样更改变为ansi？

Posted 2023-05-06

另存为的办法就不要说了，要的是新建文档打开就是ansi的格式

如果想修改txt默认编码就把（dword:00000001）的最后一位数字改成下面对应的序号，

然后把下面加粗的内容另存为reg文件，然后双击导入即可。

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\\Software\\Microsoft\\Notepad]

"iDefaultEncoding"=dword:00000001

; 1 = ANSI

; 2 = UTF-16 LE

; 3 = UTF-16 BE

; 4 = UTF-8 BOM

; 5 = UTF-8

参考技术A 网上各种方法都试验了，没有用。最后选择了安装notepad++, 将打开文本文件默认方式选为notepad++，在noepad++设置中，将新建文件编码设为ANSI格式，OK了。 参考技术B 格式-字体-脚本-选西欧语言，保存

批量将ANSI文本txt文件转换成UTF8编码格式 (vbs方法)

准备两个文件即可

conv.vbs

run.bat

 

conv.vbs源码

run.bat 源碼

rem  conv.vbs  "E:xunlian新增加的训练集博彩" "UTF-8"
conv.vbs "E:xunlian新增加的训练集博彩" "UTF-8"

　　

bat和vbs放到一起，bat内容如下：
rem conv.vbs "改为txt所在文件夹a的路径" "改为要转换成的字符编码"
conv.vbs "改为txt所在文件夹a的路径" "UTF-8"

使用实例见run.bat文件内容，注意待转换的txt文件路径，双击该文件即将执行批处理
