[TYPO3-bugs] Possible bug in translation

[Tim Wendisch]

Hi all,
I am setting up a big Typo3 installation with different language and google 
maps etc.. These language are: german, french, russian, japanese, chinese, 
etc.

While i tried to implement the chinese (simplyfied) i found out the typo3 is 
using "ch" as language code for this translation. If I use the code below 
for installation, the translations for the different extensions (translated 
manually with the extension llxmltranslate)work BUT google maps is still in 
english becourse the given language parameter is wrong. (for google maps it 
is &hl=)( in this case &hl=ch)

config{
    htmlTag_langKey = ZH-cn
    metaCharset = utf-8
    locale_all = zh_cn.utf8
    sys_language_uid = 9
    language = ch
}

If I change the code in the correct (correct for googlemaps) way then the 
translations cannot be found anymore
the correct code would be:

config{
    htmlTag_langKey = ZH-cn
    metaCharset = utf-8
    locale_all = zh_cn.utf8
    sys_language_uid = 9
    language = zh-cn
}

Is this a bug or my own mistake?
