Save file in STC and utf-8

#1

I use STC with persian character but when use SaveFile() I get the empty file I forced use open a file in utf-8 encode and then use GetText() method to save file in it
are you see this problem too?

#2

Do you think your problem is related to this?

SaveFile seems to save the text in the OS-specific encoding (in my case, sjis (cp932) in windows 10 JP).
