Reuters Unicode Applet

To view this page, you should have the most recent Java installed 32-bit JRE (Java Runtime Environment) 1.8.0_102. Use the Firefox browser for best results.
This Applet will run online in your browser, but it is a hybrid you can also download, install and run it on your own machine as standalone application. It will start and run faster if you do that. It will also work safely even if you have disabled Java in your browser.

Reuters Java Test for Unicode™ Standard Support

Reuters is an international company committed to delivering news and financial information in all major languages. The Unicode Standard is capable of representing all characters from all languages and its use can greatly improve multi-language program development. Java uses the Unicode Standard to represent all characters. Reuters have kindly provided this Applet for displaying Unicode.

The Unicode Standard is capable of representing all characters from all languages and its use can greatly improve multi-language program development. Java uses the Unicode Standard to represent all characters.

Unicode Test Applet

In the applet shown below (Java enabled browsers only) 256 characters of the possible 4096 are displayed in a grid. By clicking on the bottom and right sliders the offset of this character window into the Unicode character set can be changed. This version shows the 16-bit characters 0x0000 to 0xFFFF. It does not show the high 32-bit characters.

Applet failed to run. No Java 1.8 or later plug-in found.

Java Requirements and Troubleshooting

Unicode is a signed Java Applet (that can also be run as an application) to Unicode. You are welcome to install it on your own website. If it does not work…
  1. For this Applet hybrid to work, you must click grant/accept/always run on this site/I accept the risk to give it permission to allow you to set the look & feel and to turn on anti-aliased fonts. If you refuse to grant permission, the program may crash with an inscrutable stack dump on the console complaining about AccessController.checkPermission.
  2. In the Java Control Panel security tab, click Start ⇒ Control Panel ⇒ Programs ⇒ Java ⇒ Security, configure medium security to allow self-signed and vanilla unsigned applets to run. If medium is not available, or if Java security is blocking you from running the program, configure high security and add http://mindprod.com to the Exception Site List at the bottom of the security tab.
  3. Often problems can be fixed simply by clicking the reload button on your browser.
  4. Make sure you have both JavaScript and Java enabled in your browser.
  5. Make sure the Java in your browser is enabled in the security tab of the Java Control panel. Click Start ⇒ Control Panel ⇒ Programs ⇒ Java ⇒ Security ⇒ Enable Java Content in the browser.
  6. This signed Java Applet (that can also be run as an application) needs 32-bit or 64-bit Java 1.8 or later. For best results use the latest 1.8.0_102 Java.
  7. You also need a recent browser.
  8. It works under any operating system that supports Java e.g. W2K, XP, W2003, Vista, W2008, W7-32, W7-64, W8-32, W8-64, W2012, W10-32, W10-64, Linux, LinuxARM, LinuxX86, LinuxX64, Ubuntu, Solaris, SolarisSPARC, SolarisSPARC64, SolarisX86, SolarisX64 and OSX
  9. You should see the Applet hybrid above looking much like this screenshot. If you don’t, the following hints should help you get it working:
  10. Optionally, you may permanently install the Canadian Mind Products code-signing certificate so you don’t have to grant each time.
  11. If the above Applet hybrid appears to freeze-up, click Alt-Esc repeatedly to check for any buried permission dialog box.
  12. If you have certificate troubles, check the installed certificates and remove or update any obsolete or suspected defective certificates. The only certificate used by this program is mindprodcert2016dsa.cer.
  13. Especially if this Applet hybrid has worked before, try clearing the browser cache and rebooting.
  14. To ensure your Java is up to date, check with Wassup. First, download it and run it as an application independent of your browser, then run it online as an Applet to add the complication of your browser.
  15. If the above Applet hybrid does not work, check the Java console for error messages.
  16. If the above Applet hybrid does not work, you might have better luck with the downloadable version available below.
  17. If you are using Mac OS X and would like an improved Look and Feel, download the QuaQua look & feel from randelshofer.ch/quaqua. UnZip the contained quaqua.jar and install it in ~/Library/Java/Extensions or one of the other ext dirs.
  18. Upgrade to the latest version of Internet Explorer or another browser.
  19. Click the Information bar, and then click Allow blocked content. Unfortunately, this also allows dangerous ActiveX code to run. However, you must do this in order to get access to perfectly-safe Java Applets running in a sandbox. This is part of Microsoft’s war on Java.
  20. Try upgrading to a more recent version of your browser, or try a different browser e.g. Firefox, SeaMonkey, IE or Avant.
  21. If you still can’t get the program working click the red HELP button below for more detail.
  22. If you can’t get the above Applet hybrid working after trying the advice above and from the red HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email atemail Roedy Green.

Explanation

The slider at the base represents the first of the four hex digits of a Unicode character. The right-hand slider represents the second digit. The grid of 256 cells should show the 256 characters whose Unicode codepoints start with those two hex digits and the position in this grid makes up the third and fouth digits.

If you click on one of the characters, it will be displayed in the box in the bottom right hand corner. Its full hex value will be displayed above it.

The first 256 Unicode characters are based on ISO-8859-1 (Latin 1). Many browsers are only able to display, in Java applets, these 256 Unicode characters. To test whether your browser supports more than the Latin-1 characters, try moving the sliders away from zero and zero. For instance, the ideographic characters known in Japanese as Kanji, in Chinese as Hanzi and in Korean as Hanja, start at U+4E00 (the Unicode Standard uses the prefix U+ to indicate a Unicode character). Place the bottom slider against 4, the right-hand slider against E and you should see lots of Kanji characters.

Alternatively try setting the bottom slider to 0 and the right slider to 3. In this case some Greek characters should appear.

reutersDoes your browser support the Unicode Standard?

If you were able to see Greek (U+0370 onwards), Cyrillic (U+0400 onwards), Kanji (U+4E00 onwards) or other characters that were not in the first grid, then your browser does seem to support the Unicode Standard in Java.

If you were unable to see any other characters that were not in the first grid, then your browser does not seem to support the Unicode Standard in Java, but you may simply not have the necessary fonts.

However, if by moving the sliders nothing changed then it is likely that the Java Virtual Machine in your browser is chopping the top eight bits from each 16-bit Unicode character, leaving you with a Latin-1 character. This means that your browser does not support the Unicode Standard in Java.
