Galleri -flere folders og danske karakter

Jeg har dette script som  der skal tilføres nogle flere folders til (Array) og så vil jeg gerne kunne anvende danske karakter i min foldernavne  - er der hjælp at hente her :

//GLOBALS
var gal_title = 'Gallery';    //title of the gallery

var txt_prev = '<<<';    //text "previous image"
var txt_close = 'luk';    //text "close"
var txt_next = '>>>';        //text "next image"

var img_big = '/upload/Test/galleri/galleri_big';        //folder with subfolders that contain big images
var img_small = '/upload/Test/galleri/galleri_small';    //folder with subfolders that contain small images (thumbnails)

var img_name = 'photo';        //image name (e.g. the first image is photo-001 - or if you change name to "image" then the first image name is image-001)

var ext_big = 'jpg';        //extension (filetype) for big images
var ext_small = 'gif';        //extension (filetype) for small images

var gal_cols = 5;        // how many columns per page - see how many columns you get if you change the width of gallery (#gallery,#footer width in css)
var gal_rows = 1;        // how many rows to skip before scroll starts (1 is just fine)
var imgs_height = 114 + 10;    // <.imgs class height> + (2 * 5) px for margin (see css file for height)
var comments_height = 140 + 10;    // <.comments class height> + (2 * 5) px for margin (see css file for height)

//GLOBALS - GALLERY FOLDERS ('<folder>', <number of images>, <allow comments 1 = yes 0 = no>), don't forget last array is without ,
var folders = Array (
        Array('/Døre',5,1),
        Array('/vinduer',8,0),
        Array('/Interiør',5,0)
);

//START
window.onload = function(){
    showGallery(0,folders[0][1],folders[0][0],folders[0][2]);
