diacritics in folder and place/city names

I use infolabels to show some interesting information from the exif info

Today I noticed that with Krypton the following
– when the folder name contains a diacritics (like Brazilië or Italië)
– when the place or title has a diacritics

the infolabels are not shown in Kodi (grrrr)

does more people experience these problems?
should a make a trac issuer?

This are the labels
<label>$INFO[slideshow.headline][CR]$INFO[slideshow.exifdate] $INFO[slideshow.city] ($INFO[slideshow.countrycode]) $INFO[slideshow.sublocation][CR]$INFO[Slideshow.Keywords] </label>
