◆ fetch_traits()

Fetch languages and regions from Bing-News.

150
151 # In bing the market code 'zh-cn' exists, but there is no 'news' category in
152 # bing for this market. Alternatively we use the the market code from Honk
153 # Kong. Even if this is not correct, it is better than having no hits at
154 # all, or sending false queries to bing that could raise the suspicion of a
155 # bot.
