 * File Name: connector.cfm
 * 	File Browser connector for ColdFusion.
 * 	(based on the original CF connector by Hendrik Kramer - [e-mail])
 * 
 * 	Note: 
 * 	FCKeditor requires that the connector responds with UTF-8 encoded XML.
 * 	As ColdFusion 5 does not fully support UTF-8 encoding, we force ASCII 
 * 	file and folder names in this connector to allow CF5 send a UTF-8 
 * 	encoded response - code points under 127 in UTF-8 are stored using a 
 * 	single byte, using the same encoding as ASCII, which is damn handy. 
 * 	This is all grand for the English speakers, like meself, but I dunno 
 * 	how others are gonna take to it. Well, the previous version of this 
 * 	connector already did this with file names and nobody seemed to mind, 
 * 	so fingers-crossed nobody will mind their folder names being munged too.
 *
