I'm using Spring MVC / Message to translate a java properties file in my application. All language are rendering correctly (except Japanese and Chinese.. They both appear as '?' question marks) The resulting page has a proper UTF-8 encoding.. Is it required to install a language pack to see the characters in the browser or am I encountering some other encoding issue?
I'm using this declaration for charset
They appear in my IDE / Text editors correctly on the same machine.
any thanks appreciated!
Does your response have the right Content header set? For example:
Content-Type: text/html; charset=utf-8
You say that the page has a proper UTF-8 encoding, but it's worth verifying. Next I would check the encoding of the properties files themselves. They might not be saved in UTF-8.
Also, no, you don't need a language pack to see chinese/japanese characters in a browser. As a sanity check you could google "chinese newspaper" and make sure you can see other chinese pages.

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 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 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.

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
I finally wrote me little app. It's desktop app but it has embedded web server. When I lunched it from NetBeans everything is ok. When I lunch dist jar I have correct character encoding in GUI, but web server output is corrupted ("?" instead of national characters).
I use NetBeans 6.7.1, jdk1.6.0_16, http server from Java 6 SE and lib Rome 1.0
I don't put any source code here, because I have no idea witch part should I put.
//edit:
data are hardcoded in Strings. Those Strings are passed to Rome as arguments to create RSS nodes, Romes RSS feeds are are written to String and then Strings are passed to HttpHandler.
Check the encoding in the source files.
Check any point where encoding/decoding is performed (often any place where String -> byte[] or byte[] -> String). Anything that converts bytes to Strings is performing an encoding operation myEncoding -> UTF-16.
Check that you are passing the appropriate encoding information to 3rd party libraries that perform encoding/decoding.
If generating XML, ensure that the header encoding matches the encoding used to write the bytes (<?xml version="1.0" encoding="UTF-8"?>).
If serving content over HTTP, ensure that the content type and charset header is correct (e.g. Content-Type: text/html; charset=utf-8). A charset is usually only applicable if serving a text MIME type (it is not applicable for application/rss+xml, for example). Check your MIME documentation.
This issue probably has nothing to do with NetBeans. Usually character encoding issues are due to not defining the character encoding somewhere, in which case the actual character encoding will be determined pretty much by luck.
For instance, Java Strings are UTF-16 internally, but the encoding used by Java Readers is determined by the platform default unless explicitly specified.
Just curious about the the encoding of files (the actual rendered pages). What encoding should they be in to support widest possible language space in a typical jsp type web application.
The multilingual pages should be rendered in UTF-8 encoded to maximize the chances that the user's browser can display them correctly. This is a W3C recommendation.
EBCDIC
UTF-8 supports all characters that could be used.
