A tool for finding JIS-based Japanese characters in binary data.

Usage

jstrings [options] [input]

Input can be a filename or data from stdin.

Options

-m number

Set minimum number of characters to match as a valid string. Default: 10.

-e encoding

Specify the encoding to use. Currently, the only valid value is "shift-jis". Default: shift-jis

-l

Use little-endian order for multibyte characters

-jisx0213

Use JIS X 0213 character set instead of JIS X 0208 for double byte characters

Notes

Data is output in its original encoding without any conversion. Other tools, such as iconv, can do conversion to something more useful (such as UTF8). For example:

jstrings file.bin | iconv -f SHIFT-JIS -t UTF-8 -c

To Do

• Add support for other JIS encodings: CP932, EUC
• Add support for JIS X 0212 for non-SJIS encodings (only EUC?)
• Add option to only return strings with double-byte characters present
