I would argue that you're getting hung up on the author's lack of precision. Does the file look garbled in that screenshot? Sure, I think that's a reasonable interpretation of things. Is it incorrect? That depends on what Notepad was intended to be used for. I suspect Notepad was intended from day one to be a simple means of read and editing "plain text" files written on Windows, and under that premise Notepad has always functioned perfectly.

To the author's credit, belaboring the distinction between incorrect behavior (a property of the object with respect to the intentions of its creator) and undesired behavior (an attribution given by a user with respect to their needs) would make for boring reading.

> Also, I don't know why you quoted "An issue (as perceived by a user)", since I can't find that in the article anywhere.
