Does any hashing algorithm exclude special characters?
Just tried to register at HP and here is what i got, do they store passwords as plaintext?
Of course no, as hashing algorithms work with streams of bytes, not with characters. So making some of those bytes special is a nonsense.
It's hard to tell why do they have such a weird restriction but it definitely has nothing to do with hashing.

What is the best way to implement group algebra using Matlab. More specifically, I only want to work with permutation groups (and their subgroups) but would like a way to find kernels and cosets without coding a brute force version myself.
GAP is a 'System for Computational Discrete Algebra' and is able to do all the things requested in the question.

when i print this characters in facebook status it makes a rubbish like !̸̶͚͖͖̩̻̩̗͍̮̙̈͊͛̈͒̍̐ͣͩ̋ͨ̓̊̌̈̊́̚͝͠ͅ
and it seems to be everywhere not in facebook only i searched and it was found to be "Iota" the ninth character in the Greek alphabet , does it appear rubbish because i'm pasting it with non-ascii or another format or what ?
i'm really interested to know
The font used doesn't contain that character - not every font contains every Unicode character.

I've just found this code in a comment on a blog.
#!/bin/perl -sp0777i<X+d*lMLa^*lN%0]dsXx++lMlN/dsM0<j]dsj
$/=unpack('H*',$_);$_=`echo 16dio\U$k"SK$/SM$n\EsN0p[lN*1
lK[d2%Sa2/d0$^Ixp"|dc`;s/\W//g;$_=pack('H*',/((..)*)$/)
I realise it's probably a bad idea to paste this into the terminal, but can someone untangle this and tell me what it's meant to do? I'm not even sure it's valid code :)
I found it here http://www.cypherspace.org/adam/rsa/ and it's said that it's
a perl program which implements RSA encryption and decryption,
and is small enough to use as a signature file
and here is the full explanation of the code - it uses dc (GNU desk calculator by the way).

I tried looking it up on several places. Anyone know?
I would suggest that the whole site was a custom built application however why don't you try asking them? The worst they could say is go away - hello#forrst.com
