<Multi_key> <bar> <B> is a combination and a prefix at the same time

[dniku]

There is a set of combinations that start with <Multi_key> <bar> <B>:

<Multi_key> <bar> <B> <K>    : "♚" U265A  # BLACK CHESS KING
<Multi_key> <bar> <B> <Q>    : "♛" U265B  # BLACK CHESS QUEEN
<Multi_key> <bar> <B> <R>    : "♜" U265C  # BLACK CHESS ROOK
<Multi_key> <bar> <B> <B>    : "♝" U265D  # BLACK CHESS BISHOP
<Multi_key> <bar> <B> <N>    : "♞" U265E  # BLACK CHESS KNIGHT
<Multi_key> <bar> <B> <P>    : "♟" U265F  # BLACK CHESS PAWN
<Multi_key> <bar> <B> <D> <M>    : "⛂" U26C2  # BLACK DRAUGHTS MAN
<Multi_key> <bar> <B> <D> <K>    : "⛃" U26C3  # BLACK DRAUGHTS KING
<Multi_key> <bar> <B> <S>    : "☗" U2617  # BLACK SHOGI PIECE

However, <Multi_key> <bar> <B> is already reserved for

<Multi_key> <bar> <B> : "฿" U0E3F # BITCOIN CURRENCY SIGN, ORIGINAL THAI CURRENCY SYMBOL BAHT

[inaltoasinistra]

We myght use the combination for ฿

I agree, for me it's a mystery who could need chess icons in the layout in the first place.

Since it doesn't seem like these are too popular, could we map them to something longer, like:
<Multi_key> <Multi_key> <k> <i> <n> <g>

There are a few prefix conflicts, most of which I'm blithely ignoring. Now that BITCOIN SIGN is coming into Unicode, we'll have to map it. I wonder, what about <Multi_key> <dollar> <B>, using <dollar> as a currency mnemonic? (Or remapping the chess stuff; that's also an option.)

[clsn]

Oops, actually doesn't conflict at the moment. But still, <bar> <X> is generally double-struck X, conflicting with the chess usage... something to consider.
