Error running awk program in command line: "^ backslash not last character on line"

Following the manual gawk https://www.gnu.org/software/gawk/manual/gawk.html

I'm writing the first example in visual studio code using awk extension:

awk 'BEGIN { print "Don\47t Panic!" }'

and the console are returning me this error:

^ backslash not last character on line

What could be the problem?
