Description of the Issue

In notepad++ when a comma separated text files encoding changes from ANSI to UTF-8 with no byte order marker the status bar does not reflect the change. The file needs to be closed and reopened for the status bar to reflect the change.

Steps to Reproduce the Issue

1. Load the ANSI file into NP++
2. Use a text editor, other than NP++, that can save an ANSI file as UTF-8 with no BOM
3. Go back to NP++ and allow it to reload the externally change file and note that the encoding doesn't change from ANSI to UTF-8

Expected Behavior

I expected the status bar to change from ANSI to UTF-8

Actual Behavior

The status bar stayed displaying ANSI
