    Yes, it was indeed CCed to the list. This is also CCed to the list.

    You need to look at Unicode 4.0 as well. There are 30 codepoints not
    encoded within the Hebrew block on "05" of the Roadmap. Nothing *else* is
    currently proposed for allocation to Hebrew. If a proposal is received and
    accepted, then we would look at where to allocate things. That might mean
    opening a section in "08".

    No problem. We have 16 other planes in which to put things, and Hebrew may
    spill over. There would naturally be much consideration to putting things
    on the BMP for scripts that are already allocated to the BMP, such as
    Hebrew, but space is filling up quickly.

    Right to left.

    That's OK. It has been, and sometimes still is, written right to left,
    hence it was roadmapped in a right-to-left allocation block. However, in
    modern usage, and in the Moroccan national standard now being drafted, it
    is specifically left to right. That is how it will be encoded. Hence it was
    moved away from the block of right to left scripts.

    Submit your doc whenever you are ready.

    UTC saw them. As usually happens with documents that are submitted in
    preliminary fashion, people were informed of the docs, and that you are
    receiving comments. UTC will be awaiting your updated proposals for the
    August meeting, or whenever they are ready. (This is a non-official
    response. With preliminary docs, UTC doesn't usually respond officially or
    take any recorded action.)
