character code and keyboard input question

Hi,
Does someone know if I can get a character code out of a string in a bash script?
(like 65 out of "A"...)

In general I search a way to react to single keyboard key-press - (at the moment i am using "read -n 1"), so the next question would be - what about F1..F12 and special keys like [home] [tab] aso.

Is there a better way to trigger and get keyboard input?

Greetings,

Code:

printf '%d' \"A\"

Or similarily with hexdump:

Code:

echo -n 'ABC' | hexdump -e '/1 "%d "'
