Pops one string and push its length in bytes on the stack.

This instruction can be used to get the size of a binary buffer represented by a string. For a real string with characters, it is preferable to use the String Length (multi-byte) instruction instead.

IMPORTANT NOTE

This action will not return the proper number of characters if the input string includes multi-byte UTF-8 characters.
