UnZip for non-UTF8 encoding such as cp949, sjis, gbk, euc-kr, euc-jp, and gb2312
Project description
Extract zip files that MBCS(multi-byte character set) encoded file names, such as ZIP files created in MS Windows, especially East Asian environment.
Major non-UTF8 encodings by languages: * Korean: cp949, euc-kr * Japanese: sjis (shift_jis), cp932, euc-jp * Chinese: gbk, gb18030, gb2312, cp936, hkscs, big5, cp950
Install
pip install unzipmbcs
CLI Usage
usage: unzipmbcs [-h] [-e ENCODING] cmd zipfile [target [target ...]]
unzip for non-UTF8 filenames in zip archive
positional arguments:
cmd commands: l(list), x(extract)
zipfile .zip file to unzip
target file prefix to extract
optional arguments:
-h, --help show this help message and exit
-e ENCODING, --encoding ENCODING
character encoding of filename in the .zip
API
listZip(filename, encoding=’utf-8’)
Return the information of the files in zip archive filename with character encoding
extractZip(filename, encoding=’utf-8’, filters=None)
Extract files in zip archive filename on current directory. Assume that the file names in zip archive are encoded as encoding. Only the files prefixed the values of filters list are extracted if filters are provided.
fixZipFilename(filename, enc)
Fix filename as UNICODE string which is originally encoded as enc. Works for both Python 2 and 3.
Motivation
The .ZIP format, PKZIP compression, have been widely used. Some valuable data are archived as .zip file. But, in non-ASCII, non-Western environment, it makes trouble due to filenames.
Since ZIP format was created too old (1993), there is no standard character encoding about the file name of zip archive entries. Most of zip file entries are encoded as legacy character encoding, local charset.
In modern UNICODE based environment or global data processing environment such as Linux, this makes inconvinience, less portability, mangled file names, fail to extract the file, and so on.
This module may mitigate the inconviniences.
