Hello, Michael Liddiard, Not 100% sure, but rather than trying to use the menu option Encoding - Encoding in ANSI, here is, below, a method that should work!. Anywhere, in your HTML file, just add a comment line, that contains, at least, one character, with Unicode code-point higher than x007F. Let’s say // € ( only the Euro sign, whose Unicode code-point is x20AC ). Select the option Encoding - Convert to ANSI. Save your HTML file.
I'm including the newline character ' n' in my content that I send using fprintf(). When I look at my *.txt file in a hex editor, I can see the 0x0a newline character. But when I open the file in Win 7 Notepad, the newlines are not honored. The text appears to be one continuous string. Or use Find characters in range, specifying a custom range that suits your need. 2/ Not directly. However, you can tweak Settings -> Preferences -> Editing -> Vertical Edge settings so as to locate which lines have a length higher than some threshold. 3/ Use the Search -> Find, Count tab.
Close and re-start Notepad = Your HTML file should, always, be opened, from now on, with the ANSI encoding If it works, I’ll explain, next time, the fundamental differences between the encode and convert actions Best Regards, guy038. Look, I don’t know about the technicalities, I only know what I’ve been doing for years. What you said, I’m pretty sure that’s not how it had worked before, or it’s been a damn bloody huge coincidence I never got a wrong charset for about 10 years using Notepad and ISO-8859-1 before 2016. In the years before I ALWAYS relied on the fact Notepad knew the right charset I saved or opened the file with. How it knew, I have no idea.
If I had a file with only the letter A or any ASCII characters for that matter, I wouldn’t care about charsets. Because I write in portuguese (and not in cyrillic or japanese for example), the catch is that “accented” characters (which are non-ASCII) are commonly used and are present in both UTF-8 and ISO-8859-1, but if it gets the charset wrong, the characters are all scrambled. More to the point, if I TELL the app to use one, it shouldn’t err. You’re saying the only way to know is by having special characters, but the files have to be essentially different in more than that, otherwise non-BOM UTF-8 and ISO-8859-1 wouldn’t have different filesizes.
I think part of what is in play here is that UTF-8 is the default encoding for an HTML-5 file. The characters that make up a “text” file are code points. A character encoding scheme maps the code points it understands into numbers that are stored in the file. UTF-8 and ISO-8859-1 are two different character encoding schemes. A file can technically be encoded in one or the other (or some other scheme entirely) but not in both.
However, when a file contains only code points that are encoded identically by 2 or more encoding schemes, then, unless there is some special meta-data in the file to indicate which encoding scheme is being used, the “proper” scheme is not knowable from the file’s contents. UTF-8 is a variable-length encoding (the size of the number each code point is mapped to varies); ISO-8859-1 is a fixed length encoding (the size of the number each code point is mapped to is 1 byte). Since ISO-8859-1 represents each code point in a byte, it can only encode 256 code points, the first 256 code points of the Unicode character set.
UTF-8 can be used to encode most (if not all) code points of the UNICODE character set. Code points 0 - 127 are encoded identically by the UTF-8 and ISO-8859-1 schemes. Code points 128 - 255 differ by becoming a 2-byte sequence with UTF-8 whereas they are single bytes with ISO-8859-1. So, if an ISO-8859-1 encoded file contains any code point from 128-255, then it will be a different size than a UTF-8 encoded file that contains the same code points.
I've used the log file to help in such cases. In emacs two-window mode, with the log file in one window and the tex file in the other, i can mouse-over the unidentified character in the log, then go to the tex window, ^s to search, click the middle button to enter the search argument, then return to launch the search. This requires a 3-button mouse, and sometimes several tries, but is the best approach i've found so far, since it doesn't require knowing what the unidentified character is, and the ^s search is repeatable. VIM approach I frequently have this problem when copying and pasting text. I also quite often enter accidentally an (invisibly) nonbreaking space ( ALT-SPACE on a Mac keyboard).
To identify such characters, do the following: Start with:set hls to let VIM highlight all search results. Then search with / for characters in the ASCII code range between. You can enter a character by its ASCII code by pressing CTRL-V and then enter three digits for the decimal ASCII code: / CTRL-V128 - CTRL-V255 ENTER All non-ASCII characters are highlighted, you can navigate between them with n and N as usual. To stop the highlighting of search results, use:set nohls. Probably the easiest method is to paste your text in one of the following websites: - will annotate 'weird' characters, so it gives a graphical overview of the type of characters used and helps you find the problem. This sounds similar to what you mentioned about 'characters turning red'. Works probably better, especially for a large amount of text as you don't have to manually find the characters that gives you problems.
On the other hand, it's harder to see where the problem was, which might have been handy at times.
