For further processing in a Bash script see, for example:

Capturing output of find . -print0 into a bash array

# cf. http://mywiki.wooledge.org/BashFAQ/020
unset a i
while IFS='' read -r -d $'\0' dir; do
   a[i++]="$dir"        # or however you want to process each directory
done < <(find ./ -maxdepth 1 -type d -iname 'xyz?' -print0 | LC_ALL=C sort -z)

printf '%s\n' "${#a[@]}"
printf '%s\n' "${a[@]}"

# btw, you may use printf to add zero bytes
printf '%c\000' g u b k | sort -z | tr '\0' ' '
printf '%s\000' g1 u2 b3 k4 | sort -z | tr '\0' ' '
