I am building an app that takes information from java and builds an excel spreadsheet. Some of the information contains international characters. I am having an issue when Russian characters, for example, are rendered correctly in Java, but when I send those characters to Excel, they are not rendered properly. I initially thought the issue was an encoding problem, but I am now thinking that the problem is simply not have the Russian language pack loaded on my Windows 7 machine.
I need to know if there is a way for a Java application to "force" Excel to show international characters.
Thanks
Check the file encoding you're using is characters don't show up. Java defaults to platform native encoding (Win-1252 for Windows) instead of UTF-8. You can explicitly set the writers to use UTF-8 or Cyrillic encoding.

I have an classic Java application for PC. The result of the build is a JAR file which is running on Windows machine.
The application is reading some XML files and creating an HTML document as an end result. The Xml file contains specific language characters that are not native to English.
While in development, in the IDE (Apache NetBeans 13), build - > Run the exported HTML file contains specific language characters.
When I run the JAR file, from the Project - > dist directory , HTML do not contain specific language characters.
For example characters like: č , ć , đ, š are being exported as : Ä� , while running from NetBeans they are exported as such, not as that strange symbol.
The letters in question are from Serbian, Croatian and Bosnian.
When I export the project from NetBeans, I made sure to have this option enabled:
Project -> Project properties -> Build -> Packaging where the "Copy Dependent Libraries" option is selected.
I am puzzled at this point. If anybody has any idea why something is working one way in IDE and other when exported please let me know.
The likely problem is that your HTML file needs to identify its character encoding. Nowadays, generally best to use UTF-8 as the encoding for most purposes.
Determine the file’s encoding
If you have access to the source code of your Java app, examine that to see what character encoding is being used when producing the HTML file. But I assume you have no such access.
Open the HTML file in a text-editor to examine its raw source code. See if it specifies a character encoding. If it does, and that character encoding indicator is incorrect, you will need to alter your HTML file.
If no character encoding is indicated within the HTML, you will need to experiment to discover the encoding. Open the HTML file in a web browser, then use the "view" or developer tools available in most browsers (Firefox, Safari, Edge, etc.) to explicitly switch between encodings.
If switching to a particular encoding causes the text to appear as expected, then you know the likely encoding.
Specify the file’s encoding
In the modern version of HTML, HTML5, UTF-8 is the default encoding assumed by the web browser. But if the web browser switches into Quirks Mode, the browser may assume another encoding. To help avoid Quirks Mode, a HTML5 document should start with <!DOCTYPE html>.
So, best to be explicit about the encoding. Once you determine the encoding being used by your Java app creating the HTML file, either alter that app (if you have source code) to write an indicator of the encoding, or else write another Java app to edit the produced HTML file to include the indicator. If you are not a Java developer, you could use any programming language or even a shell script to edit the produced HTML file.
To indicate the encoding of an HTML5 file, add a meta element.
For UTF-8:
<meta charset="UTF-8">
For Latin-1:
<meta charset="ISO-8859-1">
If your Java app was developed exclusively on Microsoft Windows, the developer may have knowingly or unwittingly used one of the Microsoft defined character encodings. Older versions of Java defaulted to using a character encoding specific to the host platform — but be aware in Java 18+ the default changes to UTF-8 across platforms.

You can read about these issues in many places. Like here and in Wikipedia.
If you are not savvy with character sets and character encoding, I highly recommend reading the surprisingly entertaining article, The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!), by Joel Spolsky.
I wrote a program that reads from a file has Arabic text encoded with ANSI.
I made a runnable jar of that program.
It run perfectly on my Laptop, however, when I run it on another laptop the Arabic characters turn into a messy symbols.
So what to do?
Make sure your end system is having the fonts required to display those letters if not bundle it with your application.
Check whether you are reading the file content UTF-8 (Or appropriate encoding format).
I am currently working on a project with multiple languages we also have french, the only problem is that it displays weird characters, in stead of normal french,
Can some1 help me with this ( its in java )
thanks from beforehand
If you are using Resource bundles in the ".properties" format, then this issue can be resolved by escaping al the not standard characters with their respective Unicode notation.
.propertie resource bundles are always in ISO-8859-1 encoding, so most likely you problem comes from converting the ISO-8859-1 encoding to UTF-8
You can easily convert all these characters to escaped Unicode representation by using one of these tools: native2ascii or AnyEdit
using nonstandard characters in resource bundles
It has nothing to do with the font, but the encoding. I suggest you switch to UTF-8, a good standard for international characters.
Most likely this has nothing to do with fonts, and the real problem is an encoding issue.
Read The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!)
Make sure your code uses the correct encoding whenever it converts between bytes and strings. Avoid the methods/constructors/classes that use the platform default encoding.
Please use Character Encoding Filers at server side this will resolve your issue

Character Encoding
We recently got a localization file the contains Portuguese translations of all the string in our java app. The file they gave me was a .csv file and I use file maker to create .tab file which is what we need for our purposes. Unfortunately none of the accents seem to work. For example the string vocÍ in our localization file shows up as vocΩ inside the application. I tried switching the language settings to portuguese before creating compiling but I still get this problem, anyone have any ideas of what else I might need to try?
I think that you problem is related to the file encoding used.
Java has full unicode support so there shouldn't be any problems, unless the file you are reading (the one made with FileMaker) is encoded in something different than UTF8 (which is the default used by Java).
You can try saving the file in a different encoding or specifying which encoding to use when opening it from Java (see here). Many API classes support additional parameters to specify which charset to use when opening a file. Just take a look at the documentation..
I have a Java application that is generating JasperReports. It will create as many as three JasperPrints from a single report: one prints on the printer, one is serialized and saved to the database, and the third is exported to PDF using Jasper's built-in export capability.
The problem is that when exporting to PDF, characters containing 8 or more bits (i.e. not 7-bit ASCII) are showing up as empty squares, meaning Acrobat Reader is not able to display that character. The print version is correct, and loading the database version and printing it shows up correctly. If I change the PDF exported version to a different format, e.g. XML, the character shows up fine in a web browser.
Based on the evidence, I believe the issue is something specific to font handling in PDFs, but I am not sure what.
The font used is Lucida Sans Typewriter, a Unicode monospaced font. The Windows "font" directory is listed in the Java classpath: without this step, PDF exporting fails miserably with zero text at all, so I know it is finding the font.
The specific characters not displayed are accented characters used in Spanish text: á, é, í, ó, and ú. I haven't checked ñ but I am guessing that won't work too.
Any ideas what the problem is, areas of the system to check, or maybe parameters I need to send to the export process?
The PDF encoding used for exporting was UTF-8, and apparently the font didn't support that properly. When I changed it to ISO-8859-1, every character showed up correctly in the PDF output.
In iReport, try setting the Pdf Embedded property of your TextFields to true.
I'm using Jasper Report 6, My team has spend a few days to display Khmer Unicode. I have found solution finally, and everything work as expected.

after you exported, upload your jar file to lib folder and restart your jasper server.
