UNICODE -u parameter or switch
When importing a Unicode file, LDIFDE imports the file as Unicode if it contains the Unicode identifier at the beginning of the file. If you wish to import a file as Unicode when it does not contain the Unicode identifier at the beginning of the file, you can use the -u switch in order to force it to be imported as Unicode. The default mode for exporting files is ANSI. If there are Unicode entries, they will be converted into base 64 format. To export a file into Unicode format, use the -u switch.
