I agree. However, some don't even give the character name, which
lack can be really annoying with some diacritics. My work around is to
look up the codepoint from UnicodeData.txt.

In a perfect world, perhaps 'in real time', but not immediately.
Assuming that paragraph embedding is not set to right-to-left, if I
type <U+0041 LATIN CAPITAL LETTER A, U+0628 ARABIC LETTER BEH, U+0028
LEFT PARENTHESIS, U+062C ARABIC LETTER JEEM>, on typing jeem the glyph
for U+0028 changes from concave on the right to concave on the left,
and moves from the right to the left of beh.

The idea of displaying the glyphs according to the context of the
insertion point does have much merit, but is not so straightforward if
the character picker is a separate application and so lacks the
information. Of course, the context is not as simple as left-to-right
v. right-to-left, especially for brackets.
