Wow. Picture is worth the proverbial 10000 words. :-D

My first thought is: How many bytes does Windows Explorer think this file has? Also 4?

But it does not always work

That kind of report just makes anyone that wants to help have to do more work. Please try to be more specific in why you think it doesn’t work…

But I’ll offer up a couple of ideas:

• In View (menu) -> Summary… (equivalent to your status bar double-click) it appears that the Characters (without blanks) value being reported is actually “Characters (without line-endings)”. See https://github.com/notepad-plus-plus/notepad-plus-plus/issues/3849

• There was some suggestion that a BOM (Byte Order Mark) in the file or possibly certain encodings mess with the counts. I can’t find the main reference I’m thinking about for this, but here is a secondary one: https://notepad-plus-plus.org/community/topic/13117/go-to-offset-ignores-bom

tried a couple of times but haven’t had an issue.
Do you know, that you could use the menu View->Summary to get the same dialog?
Maybe assign a shortcut?

Or does

But it does not always work

mean something different? Like not correctly working?
