I have a CSV file with special accents and save it in Notepad by selecting UTF-8 encoding. When I read the file using Java, it reads the BOM characters too.
So I want to save this file in UTF-8 format without appending a BOM initially in Notepad.
Otherwise, is there a built-in class in Java that eliminates the BOM characters that present at beginning, when reading the contents in a file?
Use Notepad++ - it is free and much better than Notepad. It will help to save text without a BOM using Encoding → Encode in UTF-8 without BOM: Notepad++ v6 and olders:
Notepad++ v7+:
When I encountered this problem in Java, I didn't find any library to parse these first three bytes (BOM). So my advice:
Use PushbackInputStream(in, 3).
Read the first three bytes
If it's not BOM (EF BB BF), push them back
Process the stream as UTF-8
I just learned from this Stack Overflow post, as #martin-geisler points out, that you can save files without the BOM in Windows Notepad, by selecting ANSI as the encoding.
I'm assuming that for more advanced uses this won't work because the resulting file is probably not the end encoding wished, but actually ANSI; but I tested and confirmed this works to save a very small .php script without BOM using only Notepad.
I learned the long, hard way that Windows' Notepad is not a true editor, although I'd like to point out for others that, despite this, it is misleadingly called up when you type "editor" on newer Windows machines, at least on one of mine.
I am currently using Emacs and other editors to solve this problem.
Use Notepad++ instead. See my personal blog post on it. From within Notepad++, choose the "Encoding" menu, then "Encode in UTF-8 without BOM".
Notepad on Windows 10 version 1903 (May 2019 update) and later versions supports saving to UTF-8 without a BOM. In fact, UTF-8 is the default file format now.

The answer is: Not at all. Notepad can't do that.
In Java you can just skip the first byte in your InputStream and be done.
You might want to try out Notepad2 or Notepad++. Those Notepad replacements have the option for you to choose whether to output BOM.
As for a Java solution, as far as I know, Java does not understand the standard UTF-8. I googled and found Java's UTF-8 and Unicode writing is broken - Use this fix that might be the solution.
We're using the utility BOMStripperInputStream.java to strip the BOM from our input if present.

Javascript export CSV encoding utf-8 issue
I know lots mentioned it's because of microsoft excel that using something like this should work
https://superuser.com/questions/280603/how-to-set-character-encoding-when-opening-excel
I have tried on ubuntu (which didn't even have any issue), on windows10, which I have to use the second posts to import, on mac which has the biggest problem because mac does not import, does not read the unicode at all.
Is there anyway I can do it in coding while exporting to enforce excel to open with utf-8? or some other workaround I might be able to try?
Thanks in advance for any help and suggestions.
Many Windows applications, including Excel, assume the localized ANSI encoding (Windows-1252 on US Windows) when opening a file, unless the file starts with byte-order-mark (BOM) code point. While UTF-8 doesn't need a BOM, a UTF-8-encoded BOM at the start of a file clues Excel that the file is UTF-8. The byte sequence is EF BB BF and the equivalent Unicode code point is U+FEFF.
i believe i have similar problem to this how to convert unicode text to utf8 text readable? but i want a python 3.7 solution to it
i am a complete newbie, i have some experience with python so i am trying to use it to make a script that will convert a Unicode file into the previous readable text it was.
the file is a bookmark file i have recovered using easeusa then i opened the bookmark file and it is writen in unicode something like "&PŽ¾³kÊ
k-7ÄÜÅe–?XBdyÃ8߯r×»Êã¥bÏñ ¥»X§ÈÕÀ¬Zé‚1öÄEdýŽ‹€†.c"
whereas previously is said something like " "checksum": "112d56adbd0caa2b3693bb0442dd16ff",
"roots": {
"bookmark_bar": {
"children":"
fyi when i click save as for the unicode bookmark file, for unicode it has ANSI and not utf-8 maybe it was saved us ANSI, i might be waffling here but i'm just trying to give you all the information you might need to help me
i am a newbie who depressingly need help
This text isn't "Unicode". It's simply gibberish.
This file has been corrupted -- it may have been overwritten with other data before you were able to recover it. It is unlikely to be recoverable.
I have about 3,500 text files, of mixed character sets: ISO-8859, UTF-8, ASCII, UTF-16, and maybe others.
I want to merge them all into one unicode text file, so I can run a Python script on it that expects it.
If I use cat, it doesn't exactly work.
What is the best way to solve this?
You could convert them up-front with a tool like iconv, or load them into Python with the correct encoding (by setting the correct encoding to open).
If you don't know what the encoding of each file is, then it is more complicated, because you'll need to detect the encoding of each file. There are many heuristics, but not absolutely standard way to do this. Again, using iconv can help a lot here.
I've changed the encoding from Eclipse but all my strings with special characters now are like this "�". The old encoding was the Default (Cp1252), now it is UTF-8. How can I fix the strings with special characters?
Thanks.
Well, imagine you switch your brain to only understand Chinese. Could you read an English text anymore?
You changed the way Eclipse interprets the bits of your sourcecode. So you need to translate the sourcecode from Cp1252 to UTF-8.
I don't know if Eclipse is able to do this, but Notepad++ is.
Open a java-file you want to change the encoding of in Notepad++.
Click on Encoding
Select Convert to UTF-8
Save the file
When you now click on Encoding again, there should be a dot in front of Encode in UTF-8
Edit: Notepad++ recognizes the used encoding, so you can read it there. Copy and Paste from Notepad++ to Eclipse won't work, because you copied the same string Eclipse couldn't read. You have to change the encoding of the string.
I run MacBook Pro under 10.6.7, and I am competent in Unix. I have old Japanese text files in various encodings (EUC, SJS, New-JIS) that I can no longer read or display. The old program jconv.c does not help, since it only converts among these encodings. Is there a way to convert them (or any one of them) to the current "normal" Japanese text that can be seen in TextEdit, etc.? I have set the Terminal preferences to SJS and EUC (can't find NewJIS), among others, including UTF-8. Eleanor
I recommend you look into iconv for doing such conversions.
nkf is a Linux command line program which can meet your requirement.
I am sure it is available at Debian. So you can download sorce code from the Net.
