fox 1.5), you can use nsiconverteroutputstream: var charset = "utf-8"; // can be any character encoding name that mozilla supports var os = components.classes["@mozilla.org/intl/converter-output-stream;1"] .createinstance(components.interfaces.nsiconverteroutputstream); // this assumes that fos is the nsioutputstream you want to write to os.init(fos, charset, 0, 0x0000); os.writestring("umlaute: \u00fc \u00e4\n"); os.writestring("hebrew: \u05d0 \u05d1\n"); // etc.
... os.close(); you can also write character arrays using the write function, although using writestring is simpler from javascript code.
