What is the meaning of "ANSI as UTF-8" in Notepad++?

Question

I confused that the meaning of "ANSI as UTF-8" in Notepad++, Is it means an ANSI files contained some characters that is identified as UTF-8 encoding in Notepad++ or else?

Answer 1

It means it is saved as UTF-8 without the BOM (Byte Order Mark) and has already been flagged as misleading.

Please see: http://sourceforge.net/p/notepad-plus/bugs/4095/ (Page since removed)

The above bug report has been removed since the time of writing. It read as follows:

“ANSI as UTF-8” is an incorrect, misleading and confusing term, which does not exist outside Notepad++. In addition, it is inconsistent with the rest of the UI. Please replace it with the correct term “UTF-8 without BOM”.
