ConTeXt MKIV bug: Chinese left aligned does not work as should

ConTeXt MKIV bug: Chinese left aligned does not work as should

Hi, Hans:

It seems that left aligned (flushright) does not work for chinese.
I attach the minimal test files in the mail.
To test the file, please download the zhfonts.tex from
http://code.google.com/p/ctxnotes/downloads/list, and the adobe
Chinese fonts.
(I also mailed you these files long ago for other problems)

taco and i looked into this

it has to do with the fact that the intercharacter spacing has more 
stretch than the leftskip and since raggedright is achieved differently 
from raggedleft, there is no easy solution; we could make raggedright 
behave like raggedleft but that would influence hyphenation too much

however, there is a way out ...

\startbuffer
1中中中中中中中中中中中中中中中中中中中中中中中中中%
中中中中中中中中中中中中中中中中中中中中中中中中中%
中中中中中中中中中中中中中中中中中中中中中中中中中%
中中中中中中中中中中中中中中中中中中中中中中中中中%
\stopbuffer

\framedtext
     [align={broad,flushright},width=90mm]
     {\getbuffer}

\framedtext
     [align={broad,flushleft},width=90mm]
     {\getbuffer}

\framedtext
     [align=middle,width=90mm]
     {\getbuffer}

some time in the future we can think of language specific defaults, like

\let\raggedleft\veryraggedleft
\let\raggedleft\veryraggedright

for chinese but first we need to investigate to what extend we need such 
language specific defaults

adapting the leftskip node in the nodelist is also an option, but that 
might have unwanted side effects so best is to keep it under user control

make sure to wikify this ...

Hi, Hans:

wikified in http://wiki.contextgarden.net/Chinese_Flush_Right
and I think Li Yanrui will put this into his ctxnote introduction:
http://code.google.com/p/ctxnotes/

And I hope there is a perfect solution soon  (it is strange that LaTeX
left/right align works good).

well, it all depends on hwo one defined raggedleft and raggedright; it
just happens that the context defaults are tuned differently

i'm pretty sure that there are more differences between context and
latex -)
