    I grew up in Hungary and I've never seen any contemporary use of rovásírás. The scholars, as far as I know, prefer LTR directionality. But than again, my information is only based on my personal experience which might be limited and somewhat outdated.

    In any case, as I mentioned earlier, the problem of glyph mirroring when inversing default text direction does not only concern rovásírás and Old Italic, but a number Phoenician-derived scripts (with both LTR and RTL default directionality), so I think the bi-di algorithm needs to be seriously revised to accommodate for this.

    No, it's written RTL 99% of the time, maybe 1% LTR. Sorry, your
    information is flawed.

    In that it differs from Old Italic. Also, Old Italic (and Hieroglyphs)
    are actually dead scripts used by scholars only. Old Hungarian is used
