    Years ago I wrote a little program that used keyboard hook techniques, which
    ran in the background, to enable me to type 'backwards', as for Hebrew and
    Arabic. This program just moved the cursor to the left automatically, so
    that I could type the Hebrew letters in the order in which you would read
    them. Of course since the font was just ASCII, with the usual L2R

    The problem now is that when the conversion to Unicode is carried out, this
    runs into the directionality inherent in Hebrew, and this has to be
    cancelled out.
