[SOLVED] Wrong characters in portlets with special characters
New Member Posts: 21 Join Date: 11/5/14 Recent Posts

I have a Liferay 7.1 Tomcat bundle in a Fedora OS. When I load a portlet with special characters (á, é, ñ...) they are showed like this:

The settings that can affect the character encoding, I have them like this:

  • Tomcat starts with parameter -Dfile.encoding=UTF8
  • In Eclipse, the JSP file uses UTF-8 encoding
  • In the web page source code I can see this tag:  <meta content="text/html; charset=UTF-8" http-equiv="content-type">.
  • Watching the System properties in the Portal Control Panel, the value of the property file.encoding is UTF-8

If I put the same text in the Language.properties file and I load it with the liferay-ui:message tag, the text appears correctly.

If I place the snippet <%@ page pageEncoding="UTF-8" %> at the top of the JSP the text appears correctly too.

I made sure with another text editor (Geany) that JSP encoding is UTF-8.

Other things I tried that haven't worked:

- I added this configuration in build.gradle file:

compileJava.options.encoding = 'UTF-8'

tasks.withType(JavaCompile) {
    options.encoding = 'UTF-8'
}

- I have tried to make a portlet using Maven.

- I have used the portal with Hypersonic DB and MySQL (with CHARACTER SET UTF-8).

Any idea?

Regards.

For URLs, UTF8 chars have to be encoded, they cannot be in the URL as-is.

Whatever is building your URL is not properly encoding the UTF8 chars.

The problem is not related with the URL. I'll give you an example.

I have this code in my view.jsp file:

<%@ include file="/init.jsp" %>

<p>Álava Épico Sísmico Metódico Lúdico España</p>

When I deploy the portlet, it is showed like this in the portal:

Álava Épico Sísmico Metódico Lúdico España

It could be the build process, packaging the files in unexpected encoding. Check the artifact JAR or WAR file: Unpack and analyze the resources in there.

In older versions, Liferay language resources (e.g. Language.properties) needed to be UTF-8 encoded. I'm not aware if this is still the case or not - but it's a potential point for confusion. Regular build tools will encode them in ISO-8859-1

After compile project (using gradlew deploy), I've unzipped de JAR generated and I've opened the view.jsp file to make sure the encoding (and it is UTF-8).

I've deployed the JAR file in the portal and I've founded the file liferay-ce-portal-7.1.1-ga2/work/org.tests.liferay-1.0.0/org/apache/jsp/view_jsp.java with this content:

package org.apache.jsp;

      out.write("\n");
      out.write("<p>Álava Épico Sísmico Metódico Lúdico España</p>\n");
    } catch (Throwable t) {
      if (!(t instanceof SkipPageException)){
        out = _jspx_out;
        if (out != null && out.getBufferSize() != 0)
          out.clearBuffer();
        if (_jspx_page_context != null) _jspx_page_context.handlePageException(t);
        else throw new ServletException(t);
      }
    } finally {
      _jspxFactory.releasePageContext(_jspx_page_context);
    }
  }
}

I think the problem is that is generating the line

out.write("<p>Álava Épico Sísmico Metódico Lúdico España</p>\n");

but I don't know why it is happening.

Finally, I found a solution.

It seems that I had to compile the project using the ISO-8859-1 encoding in the JSP file. Now the special characters are displayed correctly.

Thanks for the help!
