* is a legal character for ls but perhaps not cygpath?  I don't know.
No files or directories are using * in the name. 

Not sure about incorrect terminal settings as I never touched any.  
It shows up in mintty and ssh equally. The characters that appear vary.

Some non-existent paths do *not* produce the gibberish.

%%%cygpath -w /aaa/bbb/*
C:\cygwin\aaa\bbb\

Looks more like private character space combined with incorrect terminal setup.
