Use the following command line options:
/cp Encoding --- sets an encoding to open as.
/cps Encoding --- sets an encoding to save as.
/sa "DestFile" --- specifies a file name to save as after the encoding conversion
/ss+ --- saves the file with a Unicode signature (BOM) after the encoding conversion.
/ss- --- saves the file without a Unicode signature (BOM) after the encoding conversion.
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.
