Escaped Characters in Regular Expressions

Regex(

	"Are you there, Alice?, asked Jerry.", // source

	"(here|there).+(\w+).+(said|asked)(\s)(\w+)\." ); // regular expression

"there, Alice?, asked Jerry."

(here\|there).+	Matches “there”, a comma, and a space.
(\w+)	Matches “Alice”.
.+	Matches “?, “.
(said\|asked)(\s)	Matches “asked” followed by a space. Without the space, the match would end here; “asked” is followed by a space in the source string.
(\w+)\.	Matches “Jerry” and a period.
