Hello, @asbyonejj, @gstavi and All,
Reminders :
An ANSI encoded file is generally a file with an encoding, from Windows-1250 to Windows-1258, and codes 256 characters, divided in two parts :
Characters with Unicode code-point between \x00 and \x7F ( from 0 to 127 ), coded with 1 byte, which belongs to the old US-ASCII encoding
Characters with Unicode code-point between \x80 and \xFF ( from 128 to 255 ) which are specific to a one-bit encoding, like, for instance, the ISO-... encodings family, the OEM-.... encodings family and the Windows-.... encodings family, for the best-known
For an almost exhaustive list of encodings, refer to the table, at :
https://en.wikipedia.org/wiki/Windows-1252#External_links
An UT8 encoded file, due to the clever UTF-8 encoding ( Universal Character Set Transformation Format - 8 bits ), can encode any of the 1,114,112 possible Unicode characters with :
1 byte if the Unicode code-point of this character is between x{0000} and \x{007F}
2 bytes if the Unicode code-point of this character is between x{0080} and \x{07FF}
3 bytes if the Unicode code-point of this character is between x{0800} and \x{FFFF}
4 bytes if the Unicode code-point of this character is between x{10000} and \x{10FFF}
However, note that the last Unicode v13.0 release contains only 283,506 assigned characters and there still are 830,606 non-assigned characters, so reserved for future use !
https://www.unicode.org/versions/stats/charcountv13_0.html
You may have noticed than the encoding of the first 128 characters, between x{0000} and \x{007F}, is quite identical in an ANSI and in an UTF-8 encoded file
So, if your file contain only characters, with Unicode code-point lower than \x{0080} and that your file is not UTF-8-BOM encoded, it’s impossible to any editor, including Notepad++, to guess that the user assumes an ANSI or an UTF-8 encoding. See :
http://www.unicode.org/charts/PDF/U0000.pdf
Thus, in order to remove the ambiguity and help N++ to decide of the right user-encoding, you have two possibilities :
Include in your file, at least, 1 character, with code-point above \x{007F}
UN-tick the option Apply to opened ANSI files in Settings > Preferences... > New Document > Encoding, if the UTF-8 option is ticked
This way, after saving your file with the ANSI encoding ( Encoding > Convert to ANSI ), it will now keep this ANSI encoding for future N++ startups ;-))
