Yes I've already checked the note. But it says the parameter BYPASS_INB_HANDLER has to be removed, while we need that parameter to accomodate difference between external and internal host. So we can't use this note.
Oh and I also retest the scenario, and turns out using the codepage UTF-8 is not help. All product ID with character > and < still giving portal runtime error.
