How is having Cyrillic characters different from having an LRM?

ASCII characters are not changed by iso-8859-8 in any way, and LRM
doesn't need to be "read" at all.

You are welcome to code a function that determines when it is actually
required.  One problem with doing so with 100% accuracy is that the
outcome depends on the text that follows the string in question, and
sometimes even on text that precedes it.  These are not always known,
and in fact the text that follows will normally be unknown.
