What's the encoding in which the file is saved when I use open(filename) in Python or fopen(filename) in C?

wish help you to fix your issue A file is saved in the encoding you save it in. A source file is saved in the encoding you save it in. They don't have to be the same, they just should be declared.
Per your other question, I assume you are using Notepad++ and when you open file.txt you find that Notepad++ thinks the file is encoded in UTF-8 without BOM. This is an incorrect guess by Notepad++. Select the Chinese GB2312 character set and the file will display properly.
code :
# encoding: utf-8
import codecs
with codecs.open('file.txt','wb',encoding='utf-8-sig') as f:
    f.write(u'abc莹')

To fix this issue Okay, I kept looking around and I figured this out.
This has nothing to do with a VSCode setting, as I had thought.

To fix this issue I am trying to get the filename of the Excel file that is opened, however keep getting the full path plus the filename. For example, I keep getting: C:\some_dir\other_dir\another_dir\filename.xls when in reality, I just want filename out of filename.xls. The issue is that the user could go into many sub-directories so can't simply use a parsor since it may change every time. Thoughts?
