Encoding not retained when moving a file to a new instance.
- 
 This is just a very minor inconvenience, but when I drag and drop a file i’m editing into it’s own window it reverts back to ANSI encoding. 
 I want it to remain OEM-US. I guess I need to change the default encoding.I see an option, Settings>Preferences>New Document>Encoding, which i’ve already set to OEM-US. 
 I’ve also tried to edit and save the file with OEM-US encoding before moving it to a new instance.

 This question pertains to Notepad++ v7.5.5 32-bit, running on Windows XP. 
- 
 Hello @compu-chan and All, On my Win XP configuration, I did a test : - 
I downloaded the 7z archive of the last 7.5.8version of Notepad++
- 
I extracted all files in folder D:\Test
- 
I started N++ and I customized in Settings > Preferences..my usual settings and, particularly, theBackup > Remember current session for next launchoption
- 
As you, I set the default encoding to OEM-USencoding, inSetting > Preferences...> New document > Encoding
- 
Then, I opened several files ( change.log, license.txt, readme.txt ) 
 => Of course, the default encoding used, for existing files is ANSI- So, I changed, for instance, the encoding of the readme.txt file to OEM-US
 => And, after closing and re-starting Notepad++, I do get the same OEM-USencoding for the readme.txt file !- 
Now, I opened a console DOS window and moved to the D:\testfolder
- 
With the command notepad++.exe -multiInst, I opened a new instance of N++
 => As expected, this 2ndinstance contained all the files of the1stinstance ( current session ) and the encoding of readme.txt was, indeed,OEM-US- Then, I closed this second instance and re-opened it, without any session, with the DOS command notepad++ -nosession -multiInst
 => As expected, only a new 1file was opened, with the customized encodingOEM-US- 
I opened the readme.txt file and, this time, as you saw, the encoding of readme.txt was ANSI ! 
- 
Again, I closed this second instance and re-opened it, without any session, with the DOS command notepad++ -nosession -multiInst
- 
Now, using the Ctrl + Drag and Drop, I copied the readme.txt tab of the1stN++ instance to the2ndN++ instance
 => Again, the default encoding of the readme.txt file was ANSI
 Simply, note that this behaviour is identical, if no 2ndinstance is involved in process ! Indeed :- 
Close any supplementary instance of N++ 
- 
Now, close your 1stN++ instance
 => On re-starting N++, the readme.txt encoding is still OEM-US, according to information of thesession.xmlconfiguration file- Then close ( Ctrl + W) the readme.txt tab and re-open it with the Restore Recent Closed File command (Ctrl + Shift + T)
 As during the tests, above, with a 2ndinstance, the initialOEM-USencoding is lost and the defaultANSIencoding is chosen for the readme.txt file !
 Conclusion : You must live with this small drawback :-((. And, to my mind, if you want to keep a chosen encoding, taken from Encoding > Character Sets, for a given file, from one session to another, closing and re-starting N++, the only way seems :- 
Get the option Remember current session for next launchticked, inPreferences... > Backup
- 
Do not close the given file’s tab, before exiting N++
