Question: What are the General Categories of Unicode?
Answer: Letter, Mark, Number, Punctuation, Symbol, Separator and Other

Question: What type of use is the General Category not helpful for?

Answer: the range of code points that are available for use as characters

Question: What is an ogonek? 
Answer: a dot above

Question: How does Unicode encode characters?
Answer: associating an abstract character with a particular code point

Question: How are some abstract characters represented in Unicode?
Answer: a sequence of two or more characters

Question: What policy guaranteed that characters have a unique and immutable name?
Answer: Name Stability policy

Question: What happens when a name is defective or misleading?
Answer: a formal alias may be defined

Answer: Unicode Roadmap Committee

Question: What does the Unicode Roadmap Commmittee do? 
Answer: maintain the list of scripts that are candidates or potential candidates for encoding

Question: What proposal has been made for the Mayan script? 
Answer: no proposal has yet been made

Question: Where does the Unicode Roadmap Committee post information on these scripts?
Answer: Unicode Consortium Web site

Question: How many mapping methods does Unicode define?
Answer: two

Question: What are the two mapping methods that Unicode defines?
Answer: Unicode Transformation Format (UTF) encodings, and the Universal Coded Character Set (UCS) encodings

Question: What do numbers in the names of the encodings indicate? 
Answer: the number of bits per code value (for UTF encodings) or the number of bytes per code value

Question: What are the most commonly used encodings? 
Answer: UTF-8 and UTF-16

Question: What does UCS stand for?
Answer: Universal Coded Character Set

Question: What does BOM stand for? 
Answer: Unicode Byte Order Mark

Question: What specifies the BOM?
Answer: UCS-2 and UTF-16

Question: what is the code point of the BOM?
Answer: U+FEFF

Question: What is U+UFFE the result of? 
Answer: byte-swapping U+FEFF

Question: What is the UTF-8 standard? 
Answer: RFC 3629

Question: Byte order marks are forbidden in protocols using what standard? 
Answer: UTF-8

Question: Why is it possible to distinguish UTF-8 from other protocols?
Answer: the large restriction on possible patterns
