They (U+300C LEFT CORNER BRACKET and U+300D RIGHT CORNER BRACKET)
are bidi-neutral (bidi class ON) and have bidi-mirroring, as you should
see from the nonsense string
ب「ةذظظ」ت
(0628 300C 0629 0630 0638 0638 300D 0629), whichever the paragraph-level
embedding. Whether a top-left corner (「) should be mirrored to a
bottom-right corner (」) is a matter of taste, which will probably not
bother those who think that bidi-mirroring is a matter of character
substitution. They are listed as a pair in both BidiBrackets.txt and
BidiMirroring.txt.

Except that a visual keyboard for an RTL writing system is highly unlikely to
have U+300C and U+300D.
