And I found that if sequence is "AbiWord**##&&(here ## && are Chinese
chars too),I can't guess what's the sequence after cut&paste.Maybe
the string know the regular.:-) As I test,I select the whole string
"AbiWord**##&&".After copy&paste,it became **AbiWord##&&".Then,I
select "**AbiWord##&&",after same operation,I got "**##&&AbiWord".
Here,all Chinese chars stand ahead of English Chars.:-( I don't know
why.Maybe someone else who is familair with pieceTable know what
happened when copy operation excutes?

English chars get good sequence.If we ignore English chars,CJK chars
have good sequence too.I mean,if string is ABCDEF (Here ABCDEF stand
for six Chinese chars),their sequence is always ABCDEF after
copy&paste although between or after them there is English chars.

Yes,CJK chars get moved.:-(

As I expect,.txt and .abw file are fine.Their sequence is good.

Html file works fine.When I save .abw file as latex file,AW crashed.
I almost know nothing about latex,so I ignore the message.If you are
interested in this bug,I will test again and send the message to you.
