I'm contemplating about this very little piece of Perl code. I'm already more than a little bit proud of it, but I wondered if the venerated Monks had suggestions to make it even shorter:

print"@ARGV"=~s|.|$_=2+index'temaniowkugrdsXjyüqäxvöpcfzlbh',lc$&;$Q=
1.45*log;$_-=1<<$Q;for($O='';--$Q>0;$_/=2){$O.=chr$_%2+45}"$O "|ger
[download]

Try it with some text as command line arguments.

Especially I'm curious about:

• Is there any way to avoid initializing $O?
• I use $Q=1.45*log to approximate the number of bits in $_. Any shorter way?
