* ISO 8859-2 Character Set at http://nl.ijs.si/gnusl/cee/charset.html
This site provides almost all information about iso-8859-2,
including the character table!!! (must see!)
* ISO 8859-2 and even HTML entities !!! (must see!)
http://people.ssh.fi/mtr/genscript/88592.txt

One more table, this time it includes even information about Polish
