To view this page, you should have the most recent Java installed
32-bit JRE (Java Runtime Environment) 1.8.0_20.
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.
Helps you determine the encoding of a file by
displaying the beginning of it in hex and decoded characters in any of the supported Java
encodings. If the file is made only
of printable ASCII (American Standard Code for Information Interchange) characters, then almost any encoding can be used to read
it. If the display shows blanks between each character then chances are you have some
variant of UTF-16 encoding. The BOMs (Byte Order Marks)
can also be a clue to the
encoding. Also try the national encodings of the country where the document came from.
For HTML (Hypertext Markup Language) documents you browse of the
web, look at the declared encoding in the http-equiv=Content-Type header using Wireshark. It is often correct. A good bet is North
American Windows files will be ISO (International Standards Organisation) 8859-1, Linux files
UTF-8 and emails SO (Significant Other)
There is no mechanism to keep track of which encodingwas used to write a text file. You just have to know. The Encoding Recogniserwill help you guess. Originally this caused no problem, because people rarely exchanged files
except with coworkers. Everyone’s files were encoded in the same local national encoding. Today people share files all over the globe. It is best to use ASCII for 7-bit chars,
ISO-8859-1 for 8-bit and UTF-8 for 16-bit.
Java Requirements and Troubleshooting
is a signed Java Applet (that can also be run as an application)
to Encoding Recogniser.
You are welcome to install it on your own website.
If it does not work…
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 read a file whose encoding you want to determine.
If you refuse to grant permission, the program may crash with an inscrutable stack dump
on the console complaining about AccessController.checkPermission.
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.
Often problems can be fixed simply by clicking the reload button on your browser.
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.
This signed Java Applet (that can also be run as an application)
needs 32-bit or 64-bit Java 1.7 or later.
For best results use the latest 1.8.0_20 Java.
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 Linux LinuxARM LinuxX86 LinuxX64 Ubuntu Solaris SolarisSPARC SolarisSPARC64 SolarisX86 SolarisX64 OSX
You should see the Applet hybrid above looking much like this
If you don’t, the following hints should help you get it working:
If the above Applet hybrid 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 mindprodcert2014dsa.cer.
Especially if this Applet hybrid 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 hybrid does not work,
check the Java console for error messages.
If the above Applet hybrid 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
UnZip the contained quaqua.jar
and install it in ~/Library/Java/Extensions
or one of the other ext dirs.
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.
Try upgrading to a more recent version of your browser,
or try a different browser e.g. Chrome, Firefox, SeaMonkey, Opera, Safari or Avant.
If you still can’t get the program working
click the red HELP button below for more detail.
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 at.
Encoding Recogniser is free. Full source included.
You may even include the source code, modified or unmodified
in free/commercial open source/proprietary programs that you write and distribute. Non-military use only.
