bug#4312: 23.1; save-excursion and goto-char fail

[RSridhar]

1. I have a lisp code which saves file buffer and does some manipulation
on the 
file in shell. subsequently it is reverted. However I have tried
save-excursion 
before saving file which did not restore the file position on reverting.
So I tr
ied setq point to some var and after reverting restore point with
goto-char. Thi
s also did not ork in restoring previous position although (point)
function did 
return the correct  value from the goto-char function in lisp. 

2. The file manipulated contains utf-8 chars. Every now and then octal
values di
splay as language text but most of the time only octal utf-8 chars are
displayed
. Also the devanaagari font that is displayed incorrectly when it is
displayed..
. The (itrans) short i is to be to the left of the consonant but gets
associated
 with the right consonant. 

3. re-search-forward function fails regular expression with octal code
