It has .nfo extension but content is XML, if it helps finding the solution.

There’s your problem. Notepad++ is hardcoded to interpret .nfo file as OEM-US, because that is the official encoding of the historic DOS-era .nfo files.

If it’s really an XML file, change the extension before opening it in Notepad++

@Tyler-Durden-0 said in Japanese font not displaying in notepad++:

but bottom right says OEM-US

You probably want to choose this setting:

I tried to select this but it cannot change to UTF-8.
I have disabled “Autodetect character encoding”

BTW It has .nfo extension but content is XML, if it helps finding the solution.

Update:
Interesting, I just tried renaming the .nfo to .xml and it shows the japanese font.
So how can I fix this when opening nfo file with xml content?

but bottom right says OEM-US

You probably want to choose this setting:

Do you know what encoding the file is actually in? (UTF-8, UTF-16, or something different)?

According to windows notepad, it UTF-8,

Do you know what encoding Notepad++ interpreted it as (see the bottom right of the status bar)

Note sure which one it is, but bottom right says

Windows (CR, LF) / OEM-US / INS

Global Override is virtually never the font you want to change. Change the Default Style instead.

Yes I also changed the Default Style > Font > Consolas

Sometimes changing the Settings> Preferences > MISC. >. Direct Write and restarting Notepad++ will fix the display of Unicode characters

Just tried now and still not working
