Where it makes sense each util now has the option to show the output as a hex dump. This can be useful if you need to view the output byte-for-byte rather than as a character representation.
In the standard output, non-printable characters are now shown using a placeholder character (�) to make it easier to see what's going on.
Also, a new util has been added; a Base64 encoder and decoder. Since this is often used with binary data the above enhancements make this new util extra useful.
