Encoding cp-1252 as utf-8?

Question

I am trying to write a Java app that will run on a linux server but that will process files generated on legacy Windows machines using cp-1252 as the character set. Is there

Answer 1

If the file names as well as content is a problem, the easiest way to solve the problem is setting the locale on the Linux machine to something based on ISO-8859-1 rather than UTF-8. You can use locale -a to list available locales. For example if you have en_US.iso88591 you could use:

export LANG=en_US.iso88591

This way Java will use ISO-8859-1 for file names, which is probably good enough. To run the Java program you still have to set the file.encoding system property:

java -Dfile.encoding=cp1252 -cp foo.jar:bar.jar blablabla

If no ISO-8859-1 locale is available you can generate one with localedef. Installing it requires root access though. In fact, you could generate a locale that uses CP-1252, if it is available on your system. For example:

sudo localedef -f CP1252 -i en_US en_US.cp1252
export LANG=en_US.cp1252

This way Java should use CP1252 by default for all I/O, including file names.
