How do I set up my app to display its name in Chinese?

Within my app-descriptor.xml

<name>

        <text xml:lang="en">Appname</text>

        <text xml:lang="es">ESAppname</text>

        <text xml:lang="ch">背痛</text>

        <text xml:lang="zh_CN">背痛</text>

        <text xml:lang="zh_TW">背痛</text>

    </name>

When the iPhone language is set to English, or Spanish, the app name is displayed correctly, but for Chinese Simplifled it reverts back to displaying the English name.

Would anyone know how to achieve this?

Using AIR 16 as 17 currently has bug issues for me.

Thanks,

Mark
