Get encoding of a file in Windows

Open up your file using regular old vanilla Notepad that comes with Windows.
It will show you the encoding of the file when you click "Save As...".
It'll look like this:

Whatever the default-selected encoding is, that is what your current encoding is for the file.
If it is UTF-8, you can change it to ANSI and click save to change the encoding (or visa-versa).

I realize there are many different types of encoding, but this was all I needed when I was informed our export files were in UTF-8 and they required ANSI. It was a onetime export, so Notepad fit the bill for me.

FYI: From my understanding I think "Unicode" (as listed in Notepad) is a misnomer for UTF-16.

If you have "git" or "Cygwin" on your Windows Machine, then go to the folder where your file is present and execute the command:

file *

This will give you the encoding details of all the files in that folder.

The (Linux) command-line tool 'file' is available on Windows via GnuWin32:

If you have git installed, it's located in C:\Program Files\git\usr\bin.

Example:

    C:\Users\SH\Downloads\SquareRoot>file *    _UpgradeReport_Files;         directory    Debug;                        directory    duration.h;                   ASCII C++ program text, with CRLF line terminators    ipch;                         directory    main.cpp;                     ASCII C program text, with CRLF line terminators    Precision.txt;                ASCII text, with CRLF line terminators    Release;                      directory    Speed.txt;                    ASCII text, with CRLF line terminators    SquareRoot.sdf;               data    SquareRoot.sln;               UTF-8 Unicode (with BOM) text, with CRLF line terminators    SquareRoot.sln.docstates.suo; PCX ver. 2.5 image data    SquareRoot.suo;               CDF V2 Document, corrupt: Cannot read summary info    SquareRoot.vcproj;            XML  document text    SquareRoot.vcxproj;           XML document text    SquareRoot.vcxproj.filters;   XML document text    SquareRoot.vcxproj.user;      XML document text    squarerootmethods.h;          ASCII C program text, with CRLF line terminators    UpgradeLog.XML;               XML  document text    C:\Users\SH\Downloads\SquareRoot>file --mime-encoding *    _UpgradeReport_Files;         binary    Debug;                        binary    duration.h;                   us-ascii    ipch;                         binary    main.cpp;                     us-ascii    Precision.txt;                us-ascii    Release;                      binary    Speed.txt;                    us-ascii    SquareRoot.sdf;               binary    SquareRoot.sln;               utf-8    SquareRoot.sln.docstates.suo; binary    SquareRoot.suo;               CDF V2 Document, corrupt: Cannot read summary infobinary    SquareRoot.vcproj;            us-ascii    SquareRoot.vcxproj;           utf-8    SquareRoot.vcxproj.filters;   utf-8    SquareRoot.vcxproj.user;      utf-8    squarerootmethods.h;          us-ascii    UpgradeLog.XML;               us-ascii
