Have an ant build script which builds some java files. These files may have existed in a windows environment previously, though I am attempting to build and compile them on OSX. The file in question seems to be encoded with the following
u'Western (Windows 1252)'
The error I receive is
error: unmappable character for encoding UTF8
Does anyone have experience rectifying these types of issues?
Open the file with a text editor that allows good control over coding, such as Emacs, and save the file in UTF-8.

I'm trying to build my java project using ANT.
While running ant command i get the following error:
error: unmappable character for encoding Cp1252
I have also refrered to previous posts related to this same very query on here and as suggested added 'encoding' attribute to javac property as
<javac ..... encoding="UTF-8"> .... </javac>
which in turn gives me the following error:-
error: unmappable character for encoding UTF-8
I cannot make any changes to my code so i was hoping if there was any other solution to this.
Using a text editor like Notepad++, you can find out the encoding of the java code your are trying to compile, and pass the encoding to the ant compiler.
This thread maybe useful : Notepad++ can recognize encoding?
You need to define the encoding of your project sources, because likely contain both CP1252 and UTF-8 files, so you need to fix it. The error message should tell you the filename and the position where the illegal sequence occurred. You should then open the file with your usual editor (that hopefully stores the encoding somewhere) and transcode it to the target encoding.
In the case of the first error message consider that CP1252 is a fixed length, single byte encoding, and from this CP1252 table it seems only a few bytes don't represent any character:
0x81
0x8D
0x90
0x9D
You can open the file with a hex editor and identify the first occurrence of one of these bytes to help you guess the charset if it's neither CP1252 nor UTF8 and you absolutely can't figure out what it is.
I have a program that writes text data to files. When I run it from netbeans the files are in a correct encoding and you can read them with a notepad. When I run it from cmd using java -cp ....jar the encoding is different.
What may be the issue??
ps. I've checked that the jre. versions are the same that executes (v 1.8.0_31)
Netbeans startup scripts may specify a different encoding than your system default. You can check in your netbeans.conf.
You can set the file.encoding property when invoking java. For example, java -Dfile.encoding=UTF8 -cp... jar.
If you do not want to be surprised when running your code on different environments, even better solution would be to specify the encoding in your source code.

I have a Java file with a non-UTF-8 character in one of the comments. I've changed the file's character encoding to be UTF-8, but I don't get a compile error on that line. Is it possible to configure Eclipse's Java compiler to give me a compile error when it sees a non-UTF-8 character in a Java file?
I have seen numerous of questions like mine but they don't answer my question because I'm using ant and I'm not using eclipse. I run this code: ant clean dist and it tells me numerous times that warning: unmappable character for encoding UTF8.
I see on the Java command that there is a -encoding option, but that doesn't help me cuz I'm using the ant.
I'm on Linux and I'm trying to run the developer version of Sentrick; I haven't made no modifications to anything, I just downloaded it and followed all their instructions and it ain't makes no difference. I emailed the developper and they told me it was this problem but I suspect that it is actually something that gotta do with this error at the end:
BUILD FAILED
/home/daniel/sentricksrc/sentrick/build.xml:22: The following error occurred while executing this line:
/home/daniel/sentricksrc/sentrick/ant/common-targets.xml:83: Test de.denkselbst.sentrick.tokeniser.components.DetectedAbbreviationAnnotatorTest failed
I'm not sure what I'm gonna do now because I really need for it to work
Try to change file encoding of your source files and set the Default Java File Encoding to UTF-8 also.
For Ant:
add -Dfile.encoding=UTF8 to your ANT_OPTS environment variable
Setting the Default Java File Encoding to UTF-8:
export JAVA_TOOL_OPTIONS=-Dfile.encoding=UTF8
Or you can start up java with an argument -Dfile.encoding=UTF8
The problem is not eclipse or ant. The problem is that you have a build file with special characters in it. Like smart quotes or m-dashes from MS Word. Anyway, you have characters in your XML file that are not part of the UTF-8 character set. So you should fix your XML to remove those invalid characters and replace them with similar looking but valid UTF-8 versions. Look for special characters like @ © — ® etc. and replace them with the (c) or whatever is useful to you.
BTW, the bad character is in common-targets.xml at line 83
Changing encoding to Cp 1252 worked for my project with same error. I tried changing eclipse properties several times but it did not help me in any way. I added encoding property to my pom.xml file and the error gone. http://ctrlaltsolve.blogspot.in/2015/11/encoding-properties-in-maven.html
I import a Java project from Windows platform to Ubuntu.
My Ubuntu is 10.10, Gnome environment: My LANGUAGE is set to en_US:en
My terminal's character encoding is: Unicode (UTF-8)
My IDE is eclipse and text file encoding is: GBK.
In source file, there are some Chinese constant character.
The project build successful on Windows with ant,
but on Ubuntu, I get compile error:
illegal character: \65533
I don't want to use \uxxxx format as the file is already there,
And I've tried the -encoding option for javac, but still can't compile.
I think the problem lies not with Ubuntu, Ubuntu's console, Javac or Eclipse but with the way you transfer the file from windows to Ubuntu. You have to store it as utf-8 before you copy it to Ubuntu otherwise the codepoint-information that is set in your Windows your locale is already lost.
Did you specify the encoding option of the <javac> task in your build.xml?
It should look like this:
<javac encoding="GBK" ...>
If you haven't specified it, then on Windows it will use the platform default encoding (which is GBK in your setup) and on Linux it will use the platform default encoding (which is UTF-8 in your setup).
Since you want the build to work on both platforms (preferably without changing the configuration of either platform), you need to specify the encoding when you compile.
You need to convert you source codes from you windows codepage to UTF-8. Use iconv for this.
