This type is used to indidcate how confident the detection module about
|
||||||
|
the return result.
|
||||||
|
|
||||||
|
eNoAnswerYet is used to indidcate that the detector have not find out a
|
||||||
|
answer yet based on the data it received.
|
||||||
|
eBestAnswer is used to indidcate 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 indidcate that the detector are 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
