"Preedit" is an intermediate text.  It is used for showing partial
result of composition.  In Japanese input methods, it is also used for
showing phonetic characters to be converted to ideographic characters,
or the current selection of ideographic characters among homonyms.

The "caret" corresponds to the cursor and it represents the current
insertion/deletion point in the preedit text.  For example, one can
erase a phonetic character in the middle of the preedit text before
the phonetic-to-ideographic (kana-kanji) conversion.
