Could UIX Internationalization support ?

Question

Hi all:
As UIX documention mentioned as follows:
Internationalization and accessibility support. UIX user interface components have built-in support for internationalization and accessibility. but we adopt following environment setting then got incorrect charset display in Jheadstart Struts/UIX application, we expected in Tabname or Display Title property could using Traditional Chinese Language:
1.MS950 in Jdeveloper Preference Encoding,
2.UTF-8 charset oracle9i database,
3.set each UIX page code to "<?xml version = '1.0' encoding = 'UTF-8'?>"
4.add these code in Web.xml :
<!-- Encoding Filter Mapping -->
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter-mapping>

Answer 1

I created a very simple UIX page (following the procedures outlined in the online help topic "Working with uiXML Pages".
I set my IE browser language preference to "Chinese China [zh-cn]", moved it up to the first language selected, so it becomes my first choice.
I did not add any of the Web.xml code you provided, and ran the application.
When the application appeared on my browser, the encoding was set to UTF-8, and pre-localized Chinese characters replaced the "Previous n record" "Next n records" strings. This UIX definitely supports internationalization to Simplified and Traditional Chinese. It all works fine for me running on Windows XP.
In your initial post you said you set your JDeveloper default charset to Big5, then manually edited the page charset to UTF-8. This is probably your problem - since you set your default IDE charset to Big5, that's the encoding of the strings you input to the UIX page. Manually changing the page and response encoding to UTF-8 does not convert the content to UTF-8, and your page content is still actually encoded as Big-5. Is there any reason you can't change the JDeveloper default charset to UTF-8? If you change the defailt JDeveloper charset the strings you input to your UIX page will automatically be encoded as UTF-8. Does your IME only work with Big5? If this is your constraint, then you will have to convert all your Big-5 characters to escaped Unicode. You can use the native2ascii JDK utility to convert your strings, or leave the encoding of the page as Big-5 (don't change to UTF-8).
But if your strings are resourced out using Resource Bundles, then you'll have to run native2ascii to convert the properties files to escaped UTF-8. You can read about the procedures for doing that in this whitepaper: http://otn.oracle.com/products/jdev/collateral/papers/10g/jdev10g_multilingual.pdf.
This paper was written for 10g, but the procedure for preparing Property Resource Bundles is the same for any version of JDeveloper, since it is is a Java Requirement that Properties files be encoded as 8859-1.
Let me know if you need further assistance.
