replace soft hyphens: \xAD, not \x00AD

I am using libreoffice Version: 4.1.4.2 Build ID: 410m0(Build:2)

The help for "find and replace" tells me that I can represent special
characters as \xXXXX where XXXX represents a special character based on its
four-digit hexadecimal code (XXXX).

I wanted to remove spurious soft hyphens from my text.

Not a single \x00AD was found but thousands of \xAD. This seems to be
related to and old bug. Is it so that the bug is fixed but not the help text?
