Hi all,

This problem was first concerned by Dirk.Haun.
and today i downloaded the newest verison of libtiff ,which is marked as
3.7.2.
and it still doesn't support unicode build.

my concern is: although , tiff file format is born without contain "unicode
text".
all information (string ,text),it contain as a ANSI text.

I was thinking some idea as follows :
In Unicode version:(probably)
text can be  transformed to unicode when it was retrieved .(by read)
text can be transformed to ANSI when it was saved by client application
which is unicode build.(by write)
(this implies that all the text to be read or saved in tiff file is ANSI
compatible. that is, 
such as english(Roman/Latin based language )).
but text in other language such as CJK,Korea Language,Chinese...will not
allowed.

Does anyone do some research on this area ?
and i since more and more softwares are word-wide oriented, why libtiff
still doesn't contain unicode build ?
I think it was a such important demand.

And in recent days ,i was working on project (unicode build).and i want to
use libtiff ...,and find such things.
and find someone(Dirk Haun) has already have such advices...
but the newest libtiff still doesn't contain Unicode build.

Dirk Haun,

I know you have done some research on this area.
and would you give me some advices & experience on how you transformed the
code. 
Any suggestions would be much appreciated.

thanks all.
