It does the following:
- Pops the number count off the stack.
- Pops the number index off the stack.
- Pops the string string off the stack.
- Pushes the substring of string starting at the index’th character and count characters in length to the
stack.
Note: If either index or count do not evaluate to integers, the result is the empty string.
This is a multi-byte aware version of ActionStringExtract. Index and count are treated as character indexes,
counting double-byte characters as single characters.
