UTF8 version of il.pl irssi script.

gistfile1.pl

#
# for all who dont like perl:
#   inputlength = "{sb length: $@L}";
#
#  with leading spaces: (3 spaces in example)
#    inputlength = "{sb $[-!3]@L}"; 
#
#  with leading char "-"
#
#    inputlength = "{sb $[-!3-]@L}"; 
#
#   you cant use numbers here. if you want to use the numbers use the 
#   perl script
#
#
# thanks to: Wouter Coekaerts <[email protected]> aka coekie
#
# add one of these 2 lines to your config in statusbar items section
# 
# the perl scripts  reacts on every keypress and updates the counter. 
# if you dont need/want this the settings are maybe enough for you.
# with the settings the item is update with a small delay.
