"ANSI" does not really make sense for the letter é. Because "ANSI" is not a specific character set.
People often use it for "their" 8 bit character set. I don't know it means in notepad++.
openfile8 uses
threadAnsi:
Code: Select all
clauses
openFile8(Filename) :-
openFile(Filename, ansi(threadAnsi)).
You could be one of the persons that have "received" utf8 as their "threadAnsi" codepage (I have not figured out who has that and why). In any case it seems that you threadAnsi codepage is not the one used to encode the file.
My guess it that it is
codepageId::codePage_windows1252, and that you will therefore receive the correct contents if you use:
Code: Select all
... = openFile(dataFile52, ansi(codepageId::codePage_windows1252))

Next version of Visual Prolog (i.e. 11) will deprecate threadAnsi and you will need to be more precise when dealing with text files.
