Abiding by government regulations

Governments often have documented standards or regulations for software applications which are marketed within their country or region.

Guideline C15

Ensure that the application addresses the government regulations of the countries or regions where it will be used.
  Example: The Government of the People’s Republic of China introduced the GB18030 national standard that specifies the required character support that software must comply with. The initial version, known as the Chinese National Standard GB 18030-2000 was published in March 2000. An updated version (GB18030-2005) was published in November 2005. Only a portion of the standard is mandatory and officially required for all software products sold in China. IBM's strategy to support GB18030 is through Unicode.
