I have a WEB System and have been asked to put emoticons for sending e-mail.
I had some problems with the database encoding that is Oracle and the NLS_CHARACTERSET was set to WE8MSWIN1252 . In order to not change the structure of the database, I have made a solution that saves the emoticons in a field of type BLOB , that is:
// pego esse valor e salvo no BD na coluna Tipo BLOB
String em = emoji.getBytes("UTF-8");
To redeem the value of emoji as String I do:
// BLOB formatado para string
String em = new String(getEmoji, "UTF-8");
If I make a System.out.printl(em) emoji usually appears on my console, but when I send this String to a value of <h:inputText/> a black diamond with ? appears.
I've been trying to resolve for some time, including changing the JBOSS settings for UTF-8 encoding, and the xhtml files are saved as UTF-8. Could someone point me in some direction towards the solution?
Update The HTML Header is as follows:
<f:view contentType="text/html; charset=UTF-8"
encoding="UTF-8"
xmlns="http://www.w3.org/1999/xhtml"
xmlns:ui="http://java.sun.com/jsf/facelets"
xmlns:h="http://java.sun.com/jsf/html"

Update
As suggested by Gustavo Fragoso I saved the emoji string # x1F354, by passing the value to the inputText the string was converted to
Update: As suggested by Gustavo Fragoso could be a problem with my browser more is not; I am using a library called jQuery-emoji-picker and my front-end works perfectly, if I click on some emoji it will normally go into the input, the problem is when I do the opposite ie if the emoji string comes from the bank or if I manually paste emoji into the value of inputText when rendering html the emoji is converted to ; I was almost certain that some configuration in JBOSS was converting any request and response to another encoding other than UTF-8; so I made a filter that forced HTTP requests into UTF-8 encoding and looked like this:
package br.com.dt.filter;
import static org.jboss.seam.ScopeType.APPLICATION;
import static org.jboss.seam.ScopeType.APPLICATION;
import java.io.IOException;
import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import org.jboss.seam.annotations.Install;
import org.jboss.seam.annotations.Name;
import org.jboss.seam.annotations.Scope;
import org.jboss.seam.annotations.intercept.BypassInterceptors;
import org.jboss.seam.annotations.web.Filter;
import org.jboss.seam.web.AbstractFilter;
@Scope(APPLICATION)
@Name("encodingFilter")
@Install(precedence = Install.BUILT_IN)
@BypassInterceptors
@Filter
public class EncodingFilter extends AbstractFilter{
/** Preform the filtering. */
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {
response.setContentType("text/html; charset=UTF-8");
request.setCharacterEncoding("UTF-8");
response.setCharacterEncoding("UTF-8");
chain.doFilter(request, response);
}
}
more unsuccessful, so I configured JBOSS in standalone.xml by placing:
system-properties
property name="file.encoding" value="utf-8"/
property name="org.apache.catalina.connector.URI_ENCODING" value="UTF-8"/
property name="org.apache.catalina.connector.USE_BODY_ENCODING_FOR_QUERY_STRING" value="true"/
/system-properties
But also without success so far.
Update:
In Web Resources - Configuration there are several configuration files of faces-config.xml and one of them is called jsf-facelets.jar and see how it is configured:
<?xml version="1.0" encoding="ISO-8859-1" ?>
<!DOCTYPE faces-config PUBLIC
"-//Sun Microsystems, Inc.//DTD JavaServer Faces Config 1.1//EN"
"http://java.sun.com/dtd/web-facesconfig_1_1.dtd">

Is this ISO-8859-1 setting the reason for this problem?
