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.

Unicode Test Applet
In the applet shown below (Java enabled browsers only) 256 characters 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.
If, Unicode, the above Unicode signed Java Applet does not work…
- Often problems can be fixed simply by clicking the reload button on your browser.
- Make sure you have both JavaScript and Java enabled in your browser.
- This signed Java Applet needs 32-bit (not 64-bit) Java 1.5 or later. For best results use the latest 1.7.0. and a recent browser.
- It works under any operating system that supports Java e.g. W2K/XP/W2K3/Vista/W7-32/W7-64/Linux/OSX
- You should see the Applet above looking much like this screenshot. If you don’t, the following hints should help you get it working:
- For this Applet to work, you must click grant/accept to give it permission to allow you to set the look & feel and to turn on anti-aliased fonts..
- Optionally, you may permanently install the Canadian Mind Products code-signing certificate so you don’t have to grant each time.
- If the above Applet appears to freeze-up, click Alt-Esc repeatedly to check for any buried permission dialog box.
- 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 mindprodcert2011dsa.cer.
- Especially if this Applet has worked before, try clearing the browser cache and rebooting.
- 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.
- If the above Applet does not work, check the Java console for error messages.
- If the above Applet does not work, you might have better luck with the downloadable version available below.
- 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.
- If you are using Microsoft Internet Explorer 7, 8 or 9, try another browser. Seriously. Microsoft has taken great pains, over and over, to screw up Java and every other multi-platform standardisation.
- If you are using Microsoft Internet Explorer 7, 8 or 9, you must click to allow blocked content permission for Active X to run. This also gives permission to Java to run. 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. Don’t put up with it! Use a different browser.
- If you are using Microsoft Internet Explorer 9, makes sure the Java Plug-In SSV helper add-in is installed and enabled.
If it is not, try reinstalling the Java JRE.
- If you have Windows 7 64-bit
and Internet Explorer 64-bit,
in theory you can use 64-bit Java,
but I never been able to get it to work.
- If you still can’t get the program working click HELP for more detail.
- If you can’t get the above Applet working after trying the advice above and from the HELP button below, have bugs to report or ideas to improve the program or its documentation, please send me an email at
.

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.
Does 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.
