Problem: Police:

Law enforcement, however, constitutes only part of policing activity. Policing has included an array of activities in different situations, but the predominant ones are concerned with the preservation of order. In some societies, in the late 18th and early 19th centuries, these developed within the context of maintaining the class system and the protection of private property. Many police forces suffer from police corruption to a greater or lesser degree. The police force is usually a public sector service, meaning they are paid through taxes.

When were police used to protect the civilian system?

Problem: Unicode can be implemented by different character encodings. The most commonly used encodings are UTF-8, UTF-16 and the now-obsolete UCS-2. UTF-8 uses one byte for any ASCII character, all of which have the same code values in both UTF-8 and ASCII encoding, and up to four bytes for other characters. UCS-2 uses a 16-bit code unit (two 8-bit bytes) for each character but cannot encode every character in the current Unicode standard. UTF-16 extends UCS-2, using one 16-bit unit for the characters that were representable in UCS-2 and two 16-bit units (4 × 8 bits) to handle each of the additional characters.
How many ASCII characters are used to make one UTF-8?

 Tanzania: Dar es Salaam was the torch's only stop in Africa, on April 13. The relay began at the grand terminal of the TAZARA Railway, which was China's largest foreign aid project of the 1970s, and continued for 5 km through the old city to the Benjamin Mkapa National Stadium in Temeke, which was built with Chinese aid in 2005. The torch was lit by Vice-President Ali Mohamed Shein. About a thousand people followed the relay, waving the Olympic flag. The only noted instance of protest was Nobel Peace Prize laureate Wangari Maathai's withdrawal from the list of torchbearers, in protest against human rights abuses in Tibet.
Where was the only African destination for the torch?
A: Dar es Salaam
