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
this. convert-meta says what to do if you read a character with its
eighth bit set. input-meta says whether to permit characters with the
eighth bit at all. output-meta determines how to display characters
with the eighth bit set: if on, they are output directly; if it is off,
such characters are displayed as a meta-prefixed escape sequence.
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 input-meta on'
bash$ bind 'set output-meta on'
The `set' commands between the single quotes may also be placed
