A. A must contain all of the characters defined in B.
B. A must be Unicode.
C. The encoded values in A must match the encoded values in B for all characters defined in B.
D. A must be a multibyte character set.
E. The encoded values in A must match the encoded values in B for all numeric and alphabetic characters in B.
Answer: AC
鉴于两种不同的字符集(A和B),关于A被认为是B的严格超集这一点,以下哪一个一定是真实的?
A、A一定包含所有B中定义的字符
C、对B中定义的所有字符来说,A中的编码值必须匹配B的编码值
A strict superset must contain all characters found in the other character set and have matching encoded values for those characters.
一个严格的超集,必须包含在其他的字符集,并匹配这些字符的编码值的所有字符。
