[Help-bash] IFS & read

[Bill Gradwohl]

I have a file that uses the tab character as the separator.

Writing a read loop against that file works just fine and I get field separation.

I converted that file by replacing the tab character with \b and changed the IFS to match and now I don't get field separation.

I also tried \x00 and \x01 and they don't work either. 

What are the allowable IFS characters as far as read is concerned?
