kernel mode printing a file

["mju s" <mju_s@hotmail.com>]

hi,
  i am some problem while printing the contents of the file with tab spaces 
in the file from the kernel mode. the tab spaces are converted to junk 
characteres if i print them inside the kernel mode with the printk.

my code snippet is :

.
.
.

fd=openptr("test.txt",O_RDONLY,0666);
len=readptr(fd,buff,sizeof(buff);
printk("%s",buff);
.
.
.

the test.txt file contain only a line of string
"this    is    test"

the space in between the string is tab spaces.

while i print the output it shows junk.

so any help is appreciated,
thks,
mju
