I wrote another script for my 010 Editor.
Like its name implies, DumpStrings will dump all the strings (ASCII and UNICODE) found in a file, or a selection in a file, to the output tab.
Strings must be at least 5 characters long (defined with a #define statement in the script).
UNICODE support is very simple for the moment: 7-bit values in a 16-bit character (MSB or LSB).
Take into account that this is not designed for large files: it will take too long. But its easy to analyze partial files without having to save the selection for analysis with another strings tool.
