For anyone playing around with keyboard remapping using loadkeys or xmodmap and wanting to find what unicode code is presently assigned to a particular key the following little shell script is useful:
echo -n "$1" | recode utf-8..utf-16le | od -An -x
This needs the recode package to be installed.
Call it something like unicode_to_hex and type something like:
./unicode_to_hex ¹²³€½¾
and you get the output:
00b9 00b2 00b3 20ac 00bd 00be
showing the hex codes for those characters. It's much faster than looking symbols up in tables. Of course it only works for codes presently assigned to keys.
