[Plugin: List Yo' Files Pro] UTF-8 for plugin

Hi, pleas do you have any idea how to run plugin with UTF-8 or any other character code suporting Western european characters.
In plugin file 88-files.php is something about it, but I am not so strong in PHP coding. THX for help.

// Set up the relative path to the item.
				// START:
				// Code suggested by Peter Liu on 7/1/2011 for encoding UTF-8 files.
				// I changed it slightly to use rawurlencode() instead of urlencode()
				// since this code fetches from the filesystem, not a URL.  See
				// php.net/rawurlencode for more on spaces and "+" symbols.
				$newPath = $path . '/' . $item;
				$temparr = explode( '/' , $linkTarget );

				// Have to assemble the path this way because we can't encode the "/" character!
				$assembledPath = "";
				for( $i = 0; $i<count($temparr); ++$i )
				{
					// Use rawurlencode() to properly encode spaces for the file system.
				   $assembledPath .= rawurlencode( $temparr[$i] ) . '/';
				}
				$newTarget = $assembledPath . rawurlencode( $item );
				// END:  Code suggested by Peter Liu.
