 * File Browser connector for ColdFusion 5.
 * (based on the original CF connector by Hendrik Kramer - hk@lwd.de)
 *
 * 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.
 *
