LEFT and RIGHT are accurate for characters that MUST NOT be mirrored in
BiDi contexts according (this applies notably to punctuation and symbols
that have a weak or contextual direction and do not force the direction of
the text encoded after them).

Those characters that MUST be mirrored according to the resolved BiDi
direction, are the only ones for which OPENING/CLOSING or BACKWARD/FORWARD
should be used instead of LEFT/RIGHT.

Note also that some characters will rotate in vertical writing modes, and
in that case they have a FORWARD/BACKWARD direction, even if those
characters do not mirror in bidirectional horizontal modes.

So a single naming avoiding LEFT/RIGHT is not desirable for all characters.
This depends on how they behave when writing direction changes each time
these characters don not have a strong direction.
