Unneeded data in executable?

[Piero]

Is there not strings for Mac?

After a quick look, it seems limited to UTF8 (you can use UTF8 in stringsext to find "other strings"…)
For PB it seems better to search for UTF16le, but you can search for multiple encodings…

Edit/PS: I am referring to your github link; generally strings (and grep) are only for ASCII
