State persecution of volunteers Chinese Wikipedia volunteers who edit on topics considered controversial by the state authorities, such as about Hong Kong protests, can face harassment and persecution. Automatic conversion between traditional and simplified Chinese characters Original situation Originally, there were virtually two Chinese Wikipedias under the names of "zh" (or "zh-cn") and "zh-tw". Generally, users from regions that used Traditional Chinese characters (such as Taiwan, Hong Kong, and Macau) wrote and edited articles using Traditional Chinese characters whereas those from regions that used Simplified Chinese characters (such as mainland China, Singapore, and Malaysia) wrote using Simplified Chinese characters. Many articles had two uncoordinated versions; for example, there was both a Traditional (法國) and Simplified (法国) article on France. Further exacerbating the problem were differences in vocabulary (particularly nouns) and writing systems, between mainland China, Taiwan, Hong Kong, and Singapore. For example, a pineapple is called in mainland China and in Hong Kong and Macau, but in Singapore and Malaysia and in Taiwan. Solution To avoid this near-forking of the project, starting around January 2005, the Chinese Wikipedia began providing a server-side mechanism to automatically convert different characters and vocabulary items into the user's local ones, according to the user's preference settings, which may be set to one of two settings that convert the script only, or one of six settings that also take into account regional vocabulary differences: Conversion is done through a set of character conversion tables that may be edited by administrators. To provide an alternative means to harmonize the characters when the server-side converters fail to work properly, a special template was created to manually convert characters and article titles in one specific page. Furthermore, page title conversion is used for automatic page redirection. Those articles previously named in different characters or different translations have been merged, and can be reached by means of both Traditional and Simplified Chinese titles. Differences with other versions of Wikipedia According to a survey conducted between April 2010 and March 2011, edits to the Chinese Wikipedia were 37.8 per cent from Taiwan, 26.2 per cent from Hong Kong, 17.7 per cent from mainland China, 6.1 per cent from United States, and 2.3 per cent from Canada. Many editing controversies arise from current and historical political events in Chinese-speaking regions, such as the political status of Taiwan, independent movement and autonomy movement of Hong Kong,
