invalid byte sequence for encoding «UTF8»

I’m trying to import some data into my database. So I’ve created a temporary table,

And now I’m trying to import the data,

But then I get the error,

How do I fix that? Do I need to change the encoding of my entire database (if so, how?) or can I change just the encoding of my tmp table? Or should I attempt to change the encoding of the file?

If you need to store UTF8 data in your database, you need a database that accepts UTF8. You can check the encoding of your database in pgAdmin. Just right-click the database, and select «Properties».

But that error seems to be telling you there’s some invalid UTF8 data in your source file. That means that the copy utility has detected or guessed that you’re feeding it a UTF8 file.

If you’re running under some variant of Unix, you can check the encoding (more or less) with the file utility.

(I think that will work on Macs in the terminal, too.) Not sure how to do that under Windows.

If you use that same utility on a file that came from Windows systems (that is, a file that’s not encoded in UTF8), it will probably show something like this:

If things stay weird, you might try to convert your input data to a known encoding, to change your client’s encoding, or both. (We’re really stretching the limits of my knowledge about encodings.)

You can use the iconv utility to change encoding of the input data.

You can change psql (the client) encoding following the instructions on Character Set Support. On that page, search for the phrase «To enable automatic character set conversion».

How to fix Invalid byte 1 of 1-byte UTF-8 sequence

I am trying to fetch the below xml from db using a java method but I am getting an error

Code used to parse the xml

Read the data using the correct character encoding. The error message means that you are trying to read the data as UTF-8 (either deliberately or because that is the default encoding for an XML file that does not specify ) but it is actually in a different encoding such as ISO-8859-1 or Windows-1252.

To be able to advise on how you should do this I’d have to see the code you’re currently using to read the XML.

If it’s anything else than UTF-8, just change the encoding part for the good one.

I was getting the xml as a String and using xml.getBytes() and getting this error. Changing to xml.getBytes(Charset.forName(«UTF-8»)) worked for me.

I had the same problem in my JSF application which was having a comment line containing some special characters in the XMHTL page. When I compared the previous version in my eclipse it had a comment,

Removed those characters and the page loaded fine. Mostly it is related to XML files, so please compare it with the working version.

I had this problem, but the file was in UTF-8, it was just that somehow on character had come in that was not encoded in UTF-8. To solve the problem I did what is stated in this thread, i.e. I validated the file: How to check whether a file is valid UTF-8?

Basically you run the command:

And if there is something that is not encoded in UTF-8 it will give you the line and row numbers so that you can find it.

I had a similar problem. I had saved some xml in a file and when reading it into a DOM document, it failed due to special character. Then I used the following code to fix it:

Let me know if it works for you.

I happened to run into this problem because of an Ant build.

Those like me who understand character encoding principles, also read Joel’s article which is funny as it contains wrong characters anyway and still can’t figure out what the heck (spoiler alert, I’m Mac user) then your solution can be as simple as removing your local repo and clone it again.

My code base did not change since the last time it was running OK so it made no sense to have UTF errors given the fact that our build system never complained about it. till I remembered that I accidentally unplugged my computer few days ago with IntelliJ Idea and the whole thing running (Java/Tomcat/Hibernate)

My Mac did a brilliant job as pretending nothing happened and I carried on business as usual but the underlying file system was left corrupted somehow. Wasted the whole day trying to figure this one out. I hope it helps somebody.
