base_unicode encodes arbitrary data into Unicode characters. Unicode character table can be specified by user.
Note: Depends on the Unicode character table used, this scheme may be inefficient for storage. Using default table, the output is a little shorter than that of base64 (7% shorter).
The user can specify a Unicode character table for encoding and decoding. A default table with Chinese characters is embedded, and its content can be found in file default_table.txt.
You can also use the index table of base64, which can be found in base64_table.txt.
./base_unicode -t base64_table.txt [FILE]
Recommended table length is a power of two.
Usage: ./base_unicode [OPTIONS]... [FILE]
If FILE is empty or '-', read from standard input.
-d
-decode
decode data
-t string
-table string
path of table (if empty, use embedded table)
-w int
-wrap int
wrap lines after n characters (0 to disable wrap) (default 80)
