Question

I have a file encoded in UTF-8 which I want to read in java, change some things in the input and print the result to terminal (standard output) and to another file. I read and write the files and write to stdout with streams constructed to interpret UTF-8 encoding.

Everything is fine when I’m manually compiling and running everything, the output file contains UTF-8 signs, the stdout also prints them to terminal.

The problem is when I want to compile and run the program using ant. The output (written to terminal) produced by ant doesn’t seem to use UTF-8 signs, as Polish diactrics are changed to ‘?’. Is there any way of forcing ant to use UTF-8? Also, can I check somehow which encoding is it using at present?

I searched for an answer, but all I found was how to make ant interpret UTF-8 encoded .java files.

Answer 1

You could try setting -Dfile.encoding=UTF-8 this will set the encoding to UTF-8.

You may also want to check if your console encoding is UTF-8 (depends on the OS).
