How to generate java .properties files in python

  1. Hi all,

    I need to generate some java .properties files in Python (2.6 / 2.7).
    It's a simple format to store key/value pairs e.g.


    The key/value are unicode strings. The annoying thing is that the
    file is encoded in ISO 8859-1, with all non Latin1 characters escaped
    in the form \uHHHH (same as how unicode characters are escaped in

    I thought I could use the "unicode_escape" codec. But it doesn't work
    because it escapes Latin1 characters with escape sequences of the form
    \xHH, which is not valid in a java .properties file.

    Is there a simple way to achieve this? I could do something like this:

    def encode(u):
    """encode a unicode string in .properties format"""
    return u"".join(u"\\u%04x" % ord(c) if ord(c) > 0xFF else c for c
    in u).encode("latin_1")

    but it would be quite inefficient as I have many to generate.
