Now i'm using poi 3.11.
org.apache.poi.hwpf.usermodel.CharacterRun (for *.doc files) has both isStrikeThrough() and isDoubleStrikeThrough(), but org.apache.poi.xwpf.usermodel.XWPFRun(for *.docx files) has only isStrike() method.
it seems that isStrike() method can't detect double-struck state.
i know that double-struck state can be detected with this implementation below
but it is not pleasant for me. Are there any unified interfaces, classes or methods?
