Description of the Issue

I have export files which displayed as "UTF-16 LE" in Windows-Notepad.
This program show all chars correctly but I need the functionality of line sorting from Notepad++.
NPP show wrong sign for e.g.: "⁇�"
NPP show the file encoding "UCS-2 LE". This seams to be ok.

I canot use NPP for this file with this encoding.
What I have to do to work with my export files with this encoding?

Steps to Reproduce the Issue

1. Open the file:
   ⁇🅟-Language.csv.txt
   with Notepad and with NPP and compare the content visually.

Expected Behavior

The chars should show correctly and save with minimal changings should create a valid usable file with neccessary chars.

Actual Behavior

Work with this file will destroy the content of this file.
