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.

Then,do anyone else can teach me how to show the string which hide
in pDocRange of AP_UnixApp::copyToClipboard(PD_DocumentRange *
pDocRange) of ap_UnixApp.cpp."copyToClipboard" exec this:
***pExpRtf->copyToBuffer(pDocRange,&bufRTF);***
So,I put a debugmsg instruction in
IE_Exp::copyToBuffer(PD_DocumentRange * pDocRange, UT_ByteBuf * pBuf).
Here is the debug instruction:
UT_DEBUGMSG(("Belcon:in
IE_Exp::copyToBuffer,pBuf=%s\n",pBuf->getPointer(0)));
But I only got "pBuf=(null)".
I am not familar with these function.So,would someone else be kind
enough to show me how to output the string which I have selected
and which is copied to clipboard?
I sorry for my English.I am afraid that what I said will confuse you
all.But I am really need you help to solve the last problem of AW
CJK version.

Sorry.I mean that we can add a menu item to AW.This menu can
popup a widget which contains a list and something else.In this
list,there is all Truetype Font that your system have installed.
you can choose which font or all font to be installed into AW.
Then AW can generate some fonts.dir files according the fonts'
encoding method in different subdirectories.
You know that we can't guess what Truetype font that user has
installed,so we have to generate special fonts.dir(like
GB2312/fonts.dir or Big5/fonts.dir) when user use AW.

No,I don't mean this.The reason is above.
