Re: Freemarker Encoding issue

If you are using FreemarkerServlet (sounds like it), you probably need to set the output encoding param in your web.xml

      <servlet>
            <servlet-name>Freemarker</servlet-name>
            <servlet-class>
                  freemarker.ext.servlet.FreemarkerServlet</servlet-class>
            <init-param>
                  <param-name>TemplatePath</param-name>
                  <param-value>/</param-value>
            </init-param>
            <init-param>
                  <param-name>default_encoding</param-name>
                  <param-value>UTF-8</param-value>
            </init-param>
            <init-param>
                  <param-name>output_encoding</param-name>
                  <param-value>UTF-8</param-value>
            </init-param>
            <load-on-startup>1</load-on-startup>
      </servlet>

Of course, UTF-8 would be whatever encoding you are actually targeting.  I'm not entirely sure that this matters, but make sure that the physical .ftl file itself is saved with the correct encoding and not just ISO-8859-1.  And you might also need the meta tag at the top of the page:

<meta http-equiv="Content-Type" content="text/html; charset=UTF-8"></meta>

We have Chinese characters working from database to page end to end, so it is definitely possible.  It was a challenge to get right - difficult to pin point at what point in the chain they were getting lost.

Subject: Re: [FreeMarker-user] Freemarker Encoding issue

I tried as you say, ${"\x6464"} is still output as a '?'. And I have debug my servlet to make sure that the string in java is correct, i.e., do not contain any '?'.
So I want to know how should I set the configuration for FreeMarker and java.io.Writer?
Thank you.

Best regards,

Put a ${"\x6464"} into your template. If in the browser it shows a "?"
instead of a chinese character, then something is still wrong with the
FreeMarker configuration and/or with the java.io.Writer where
FreeMarker prints its output. If ${"\x6464"} shows a chinese
character, and also the chiense text entered directly into the
template shows correctly, then most probably it's the connection to
the data-base server that has an encoding issue. (You can double-check
that if in Java (not in FreeMarker) you log the character codes of the
string... if it contains 63-s, which is the code of '?', the it
already contains the '?'-s when you receive it from the database.)
