DEPRICATED FUNCTIONS

The "PHP4/5 - LFS Hostname codepage converter v2" is a function that allows you to convert the different character codepages in LFS hostnames to something you can use on a webpage (ie. conversion to a single codepage, the one you use on your website).
This function is a new one. I had posted one a while back that required the inclusion of a codepage conversion table. But now this is no longer required. Instead you need to have compiled the mbstring library into your PHP install. This will take care of all conversions.
After you have converted a hostname with this function, the only remaining thing left is converting the colour codes (not done in this function).
Two notes about the function below :
1) You will notice this function also replaces the special characters in LFS text such as ^d (\), ^s (/), etc. This is required because not all of these converted characters exist in the same place in every codepage. So they need to be converted from LFS escaped to actual character and then to the appropriate codepage.
2) The function takes two parameters. $str and $conv_to, which is UTF-8 by default. It is here that you indicate to which codepage you want to convert your hostname.
If you use a single byte codepage such as ISO-8859-1 on your website, you should use the HTML-ENTITIES codepage to convert your hostnames into.
For a list of all codepages supported by mbstring, see here : http://nl3.php.net/manual/en/ref.mbstring.php
