Bug: Double-byte characters don't show correctly on the preview pane

### Description

If you use shift-jis as character code in the text and you select the text file in the Files, the characters will be garbled and you won't be able to read them in the preview screen. If you use UTF-8 as character code in the text file, you will have no garbled characters and can read them normally in the preview screen. I will be grateful if you could fix it.
Thank you.

### Steps To Reproduce

1. Write something in the text file using Shift-jis as character code and save it.
2. Open Files and you select the text file and see the preview screen on the right side.
3. You will see the characters are garbled and you can not read them properly.

Windows 11 Pro 23H2
OS 　22635.3420
Windows Feature Experience Pack 1000.22700.1003.0

### Requirements

The expected behaviour will be that you can see the characters in the text file on the preview screen of "Files" even when you use Shift-jis as character code.
Fix the issue when you see garbles characters on the preview screen of "Files" if you use Shift-jis as character code. (or if you use non-2bytes character code such as Shift-jis in you will see the issue. If you use 2bytes character codes such as utf-8, you will not see the issue on the preview screen.)
