This type is used to indicate how confident the detection module about
the return result.
eNoAnswerYet is used to indicate that the detector have not find out a
answer yet based on the data it received.
eBestAnswer is used to indicate that the answer the detector returned
is the best one within the knowledge of the detector.
In other words, the test to all other candidcates fail.
For example, the (Shift_JIS/EUC-JP/ISO-2022-JP) detection
module may return this with answer "Shift_JIS "if it receive
bytes > 0x80 (which make ISO-2022-JP test failed) and byte
0x82 (which may EUC-JP test failed)
eSureAnswer is used to indicate that the detector is 100% sure about the
answer.
Exmaple 1; the Shift_JIS/ISO-2022-JP/EUC-JP detector return
this w/ ISO-2022-JP when it hit one of the following ESC seq
ESC ( J
ESC $ @
ESC $ B
Example 2: the detector which can detect UCS2 return w/ UCS2
when the first 2 byte are BOM mark.
Example 3: the Korean detector return ISO-2022-KR when it
hit ESC $ ) C
