How to properly escape single quotes in filenames?

I have files with single quotes in their name, say o'a. I want to process them in awk (gawk-5.3.0): (fd is an alternative to find). Please don't tell me about fd -x option, my command is snippet of a larger one and I am really interested in the awk solution.

fd . | awk '{ print "name: \047" $0 "\047"; cmd="stat -c \"%U\" " $0 ; cmd | getline result ; print result }'

and I get errors:

name: 'o'a'
sh: -c: line 0: unexpected EOF while looking for matching `''
sh: -c: line 1: syntax error: unexpected end of file

How to properly escape the quotes in the name in awk ? I tried with gsub but nothing has worked so far.

There are also files with $ sign, so the best solution would be to sanitize names for most of worse situations which of course will occur!

The shell does not interpret contents of single-quoted strings.

The only unacceptable character in a single-quoted string is single-quote.

Standalone single-quotes can be safely passed to the shell if escaped by a backslash.

So:

fd . | awk -v q=\' '
    function enquote(unsafe,    s){
        s = unsafe
        gsub(q, "&\\\\&&", s)
        return q s q
    }
    {
        print "name: " q $0 q
        cmd = "stat -c %U " enquote($0)
        cmd | getline
        print
        close(cmd)
    }
