Using regex \b in Find And Replace does not yield expected result


When I search for “\b” and replace all with something, it does not do what I expected. It returns the correct found results, but does not replace them with the specified replacement.

Example: (double quotes are not included in the actual input):
Text in TextEditor: “abc def ghijkl”

Find: “\b” (with regex flag on)
Replace With: "%"
then hit Replace All

Expected result: "%abc% %def% %ghijkl%"
Actual result in Atom: “abc def ghijkl”
