zip all the files in the current directory recursively into foo.zip
winzip32 -a -r foo.zip *
Let's assume the data are correctly
in UTF8. Knowing the UTF8 encoding stucture, as described in note 69518.1, we
can separate the string into UTF8 characters:
61 the 1st byte's structure 0xxxxxxx implies 1-byte UTF8 code
e9,a9,ac the 1st byte's structure 1110xxxx implies 3-byte UTF8 code
e6,9d,a5 as above
e8,a5,bf as above
e4,ba,9a as above
e5,ad,a6 as above
e6,a0,a1 as above
The 2nd and 3rd byte have the structure 10xxxxxx in all 3-byte characters we
got, thus they are legal continuation bytes. And thus, the string is legal in
UTF8 from the structural point of view.
Now, let's convert the UTF-8 codes to UTF-16/UCS-2. UCS-2 codes correspond to Unicode
character numbers (U+xxxx):
61 ==> U+0061
e9,a9,ac ==> U+9A6C
e6,9d,a5 ==> U+6765
e8,a5,bf ==> U+897F
e4,ba,9a ==> U+4E9A
e5,ad,a6 ==> U+5B66
e6,a0,a1 ==> U+6821
Thus, the string contains 'a' and six CJK ideographic characters.
You can check the CJK characters using (for example):
