Auto encoding file - magic words in file

[AdamL67]

Issue Type: Feature Request

Can you enter the auto detect encoding file using a "magic word" in file,
e.g. at the beginning in the comment I write "VSCODE.ENCODING=cp852"

batch
REM VSCODE.ENCODING=cp852
ECHO ...
...
javascript
// VSCODE.ENCODING=windows1250
def Func() ...
...
SQL
-- VSCODE.ENCODING=utf8
SELECT ...

XML
<-- VSCODE.ENCODING=cp437 -->
...

VS Code version: Code 1.65.2 (c722ca6, 2022-03-10T14:33:55.248Z)
OS version: Windows_NT x64 10.0.19044
Restricted Mode: No

Two examples how difficult this might become:

batch
REM VSCODE.ENCODING=cp852

I'm using :: as comments in my Windows batch files, because that is far easier to read.

XML
<-- VSCODE.ENCODING=cp437 -->

Many XML files already have an explicit character encoding documented in them. So it should be preferred to read otherwise already available pieces of information and especially support for XML has been asked for some years ago already.

In my opinion, the focus should be on supporting charset for EditorConfig and/or supporting file extension based configs. Those features are far more flexible, one doesn't need to deal with different textual file formats etc.
