(The language need not be related to the region.) For example:\r\n>\r\n> - de: German language content, independent of region\r\n> - en-GB: English language content, for GB users\r\n> - de-ES: German language content, for users in Spain\r\n\r\n\r\nSince some languages have different type, such as Chinese Tranditional and Chinese Simplified, ISO 639-1 format only describes 1 language code \"zh\" for both Chinese languages, but we cannot fill \"zh\" for both Chinese Tranditional & Chinese Simplified at the same time.\r\n\r\nFrom Google answer, we should use \"zh-TW\" / \"zh-CN\" or \"zh-Hant\" / \"zh-Hans\" instead, but the \"Language Code\" field in qtranslate-XT setting limit 2 characters only.\r\n\r\nCould qtranslate-XT release the 2 characters limit so that we can follow what Google suggests?"}}
