UTF8, Media and nacional chars - Maybe bug, not sure

Question

I create Media object using XML like this:
if (event.type == PullParser.TEXT) {
   if(event.qname.name == "url" and event.level == 2) {
      if("{event.text.trim()}" != "")
         parserHelper.url = event.text;
if(event.qname.name == "song" and event.level == 1) {
   parserHelper.media = Media{
     source: parserHelper.url
   insert parserHelper into songs;
}i get exception:
FX Media Object caught Exception com.sun.media.jmc.MediaUnsupportedException: Unsupported media: file:///F:/Żywiołak/epopeja_wandalska.mp3
    source ='file:///F:/Żywiołak/epopeja_wandalska.mp3'

        at pl.koziolekweb.fxmusicplayer.Main$2.lambda(Main.fx:94)In my opinion problem is a '&#379;' and '&#322;' chars in filenames. I tried with other characters like &#261;,&#281;,&#347;,&#378;,&#263; etc. and results were the same.
My question is:
Is any restrictions in JavaFX on the use nacional characters or this is a bug?
