Why GB 18030 is important
The Peoples Republic of China (PRC) government requires that all language-related products introduced into the Chinese marketplace must be able to function using all the characters in GB 18030. This includes the editing and processing of all the characters, and the ability to identify and output all the characters including minority characters. Compliance is exempt for products introduced prior to March 17, 2000. Any product (including upgrades) released between March 17, 2000 and August 31, 2001 must be updated to conform to the standard. Any product released on or after September 1, 2001 must be certified by one of the government-appointed groups. Non-compliance results in the inability to sell these products in the PRC. Does your product currently fit this category? If so, what steps can you take to correct it?
