Hmm, it's very strange if you are subscribed to the list. If you haven't yet,
please subscribe.

OK.

These are GTK widgets so they should work anyway. I would be very surprised
if they didn't work.

Could you please elaboraye - in which box - in input entry or the characters
when highlighted in the document?
Does it measure the width of Ch chars correctly (i.e. if you type English
char, then Ch char, then English char - can Ch char fit between the English
ones or not)?

Could you please try this?
Also, can it be so that you fonts you are trying to use with AW are broken?
Can you use these fonts in other apps? Are they indeed Type1 fonts?

What are your ideas on fixing input of CJK chars? Have you tried them?

Quite well where - in the document?
Are there any flaws?

* What is your $LANG is set to?
* In which subdirectory did you place chinese fonts (did AW loaded them at
all? - are CJK fonts available in font selection combobox)?
* Does your iconv knows your charset (seems so, otherwise you won't see Ch
chars in GUI elements such as menu)?
* What iconv implementation do you use (the one in glibc or standalone from
libiconv?).
* Could you paste Ch chars from other apps? Could you import .txt files into
AW?
* Could you save Ch chars as .txt or copy them to other documents
* Could you print correctly in Big5?

That's expected. That patch fixes completely different things.
Could you please post a "boot log" of AbiWord? (It will be produced by AW
when it starts if it's compiled with debug enabled - and it can sched some
light on why it misbehaves).
Thank you very much for this testing. Your help is very appreciated.
-------------------
Here is quick hacking quide to AW:
AW draws characters on the screen in the function
/src/af/gr/unix/gr_UnixGraphics.cpp:GR_UnixGraphics::drawChar{s}(...)
After the expanded body of the macro CONVERT_TO_MBS gets executed, buffer
with name 'text' should contain the conversion of the UCS-2 char to current
encoding. The conversion is done in function
UT_Wctomb::wctomb_or_fallback
so you can set a breakpoint on to debug it. (just type
'b UT_Wctomb::wctomb_or_fallback'
in gdb to set a breakpoint). That function in turn uses iconv to perform
translation. Please explore whether it performs valid conversion.
Input is done in
src/af/ev/unix/ev_UnixKeyboard.cpp:ev_UnixKeyboard::keyPressEvent
In the 'else' branch of 1st if, 'e->string' should contain a just-types valid
sequence in current encoding (BWT I don't reset a shift state neither on
input from keyboard nor on output - so if it's required, this may be a
reason of all problems). Could you please explore and say whether 'e->string'
contains a valid string. Also, somewhat below there is a code:
case EV_EEMR_COMPLETE:
UT_ASSERT(pEM);
uLength=0;
ucs=new UT_UCSChar[mLength];
for(int i=0;i<mLength;++i)
{
if(m.mbtowc(wc,mbs[i]))
ucs[uLength++]=wc;
}
invokeKeyboardMethod(pView,pEM,ucs,uLength); //no char
delete ucs;
return UT_TRUE;
Does 'ucs' contain a correctly translated characters?
As for printing - see
src/af/xap/unix/xap_UnixPSGraphics.cpp:PS_Graphics::drawChars
to see how .ps file is generated (how CJK and non-CJK characters are
emitted).
