    unicode escaping problem

    Andrew Newbie

      Hi all.
      May be this question is JSF specific but I can't find solution for a five days.
      I'm using SEAM + Facelets + EJB3.
      When I post some data in Russian on <h:inputText>, I see codes of those charactrers when form redisplays instead of characters. On sun's forums I found that characters that are "dangerous" in HTML are escaped. But how can I get real characters from form.

      my code
      <h:inputText id="searchString" value="#{productOrdering.searchString}"/>

      Please help me, this is very important for me.

      Thanks

          Hadn't anyone had such a problem? Are here any people not from english-speaking country?

            See if you can ask the guy who puts up this website:

              We have 11 to support. Painful ;-)

              I have conducted a few experiments to try and solve it. I have seen that using Linux based browsers with Unicode (Mozilla, Firefox) seems to work OK. Using IE on Windows I am able to enter the Unicode, but the re-display in the inputtext shows the hex values.

              Did you try your application through different browsers? Would be interesting to know if you have the same behavior.

              Is your persistence store configured to save Unicode ? (I created my postgresql instance with "createdb -E UNICODE instancename")

              Regards

                Thanks for your reply Louis.
                I tested on FreeBSD and on Windows
                on FreeBSD:Firefox I get hex values
                on FreeBSD:Opera I get hex values
                but on FreeBSD we have russian encoding KOI8-R
                on Win:Firefox I get hex values
                on Win:Opera I get hex values
                and
                on Win:IE I get charecters on "some" encoding, not UTF-8, not cp1251 and not ISO8859-1
                :-(
                Yes my databese created with UTF-8 :-(

                So how can we solve this problem?

                again thanks for your reply

                  Page rendered with encoding ISO8859-1 on Firefox
                  and with encoding UTF-8 on IE

                  On facelets issue trucking system I found that page must be encoded with UTF-8 by default.

                  So IE show page in correct encoding, and firefox - not

                    But problem is still there:

                    if page rendered in UTF-8 I get charecters on "some" encoding, not UTF-8, not cp1251 and not ISO8859-1

                    if page rendered in ISO8859-1 I get hex values of input characters

                          Hi

                          I havent tried the filter solution above. The following
                          https://facelets.dev.java.net/servlets/ReadMsg?list=users&msgNo=1403
                          has helped me! In short it uses a JSF Phase listerner.

                          Regards

                              Without the JSF Phase listeners, I can input and show japanese characters correctly on utf-8 pages after installing facelets-1.1.11 for the seam package.
                              I recomend the newer versions of facelets.
