script tag:

fa-IR: فارسی, ایران (Persian, Iran)
nb-NO: Norsk bokmål, Norge (Norwegian bokmål, Norway)
nl-BE: Nederlands, België (Dutch, Belgium)
pt-BR: Português, Brasil (Portuguese, Brazil)
zh-HK: 中文, 中國香港特別行政區 (Chinese, Hong Kong SAR China)
zh-Hans-CN: 中文, 中国 (Chinese, China)
zh-Hant-TW: 中文, 台灣 (Chinese, Taiwan)
