 These functions are useful primitives but missing when the mbstring
 extension isn’t available. This patch adds polyfills for those few
 environments where this is the case so that WordPress code can
 unconditionally call them.

 Only UTF-8 is supported for practical reasons. Code in unsupported
 environments should convert first to UTF-8 and then call these functions.
