Use the following command line options:

For instance, if you want to convert a file from Western European (iso-8859-1) to UTF-8, use the following syntax:

emeditor.exe "windows1252.txt" /cp 1252 /cps 65001 /ss- /sa "utf8.txt"

See Encoding Constants for the list of encodings.

See Using Command Line Options for more information.

Convert multiple files with a script

We can use this PowerShell script to quickly convert all files in a directory. Open PowerShell and enter cd 'your folder path', to go to the folder which contains your files. Now enter the following lines.

$files = (Get-ChildItem -File).FullName
$files | foreach { emeditor $_ /cp 65001 /cps 65537 /ss- /sa $_ }

(Get-ChildItem -File).FullName returns an array of all file paths in the current directory. For each file, we apply the command from before to convert all files from UTF-8 to UTF-16.
