Use this testcase to attached to re-produce i18n issue

import java.io.*;


public class F {

    public static void main(String[] args) {

	char[] obj = {(char) 0xAAcf, (char) 0xFFF0, (char) 0x0E2E};
	System.out.println("obj.length=" + obj.length);

	ByteArrayOutputStream baos = new ByteArrayOutputStream();
	PrintStream out = new PrintStream(baos);
	out.print(obj);
	System.out.println("baos.size()=" + baos.size());
    }
}

EVALUATION It appears the char array is not being translated correctly. char[] obj = {(char) 0xAAcf, (char) 0xFFF0, (char) 0x0E2E} out.print(obj) makes a call to io_h.java write(b[], off, len) When I print out the size for off and len I get the following off=0 len=2 It should be: off=0 len=3 This is what Ladybird does. It seems to be throwing away last value from char array defined above. The ArrayIndexOutOfBoundsException is a valid error since the test hard codes printing of array values. When it gets to the 3 element it crashes with exception above. This could be some kind of an i18n issue. gary.collins@East 2001-06-12 Passing this bug over to I18n team. Looks to be a character encoding bug. Please run attached testcase. and you will see size differences. import java.io.*; public class F { public static void main(String[] args) { char[] obj = {(char) 0xAAcf, (char) 0xFFF0, (char) 0x0E2E}; System.out.println("obj.length=" + obj.length); ByteArrayOutputStream baos = new ByteArrayOutputStream(); PrintStream out = new PrintStream(baos); out.print(obj); System.out.println("baos.size()=" + baos.size()); } } gary.collins@East 2001-06-12 Character conversion is actually handled by the Libraries team. norbert.lindenberg@Eng 2001-06-12 Duplicate of 4457851. When the unmapped character 0xAAcf is encountered, java.nio.charset.CharsetEncoder is skipping the next character. iag@eng 2001-07-19
