Photoshop Javascript encoding error -

my code:

// _name = mz15_09 var _num = _name.slice(2,7) var _yr ="20"+ _name.slice(2,4) var _mon = _name.slice(5,7)  _layerpath = "/volumes/sv_ebv/werbung/hefte\ 3d/"+_yr+"/"+_num+"/\*daten\ für\ ebv\ _ebenen /";     _savepath = "/volumes/sv_ebv/werbung/hefte\ 3d/"+_yr+"/"+_num;     _x1 = _layerpath+"heft_mz"+_num+"_ch_r05.psd"     var fileref1 = new file(_x1)     app.open (fileref1) 

(app.open) should open given file photoshop denies so. used debugging console in estk , says:

_x1 ergebnis: /volumes/sv_ebv/werbung/hefte 3d/2015/15_09/*daten für ebv _ebenen /heft_mz15_09_ch_r05.psd  fileref1 ergebnis: /sv_ebv/werbung/hefte%203d/2015/15_09/*daten%20fu%cc%88r%20ebv%20_ebenen%20/heft_mz15_09_ch_r05.psd 

my path ist valid (even vars in it) after put in new file() command, encoding crashes. how fix this? why happen?

this not valid folder name *daten für ebv _ebenen if remove * , space end, might work
