How can I get bash to read and display eight-bit characters? 


This is a process requiring several steps.



First, you must ensure that the `physical' data path is a full eight

bits.  For xterms, for example, the `vt100' resources `eightBitInput'

and `eightBitOutput' should be set to `true'.



Once you have set up an eight-bit path, you must tell the kernel and

tty driver to leave the eighth bit of characters alone when processing

keyboard input.  Use `stty' to do this:



	stty cs8 -istrip -parenb



For old BSD-style systems, you can use



	stty pass8



You may also need



	stty even odd



Finally, you need to tell readline that you will be inputting and

displaying eight-bit characters.  You use readline variables to do

this.  These variables can be set in your .inputrc or using the bash

`bind' builtin.  Here's an example using `bind':



	bash$ bind 'set convert-meta off'

	bash$ bind 'set meta-flag on'

	bash$ bind 'set output-meta on'



The `set' commands between the single quotes may also be placed

in ~/.inputrc.
