I do not get this bug, and i can prove it with a screenshot, is there any special characters in your language?
I had another look at this. I didn't check all characters but I can say that if one of these characters
Ä
ä
Ü
ü
Ö
ö
ß
+
are used either in a directory or in a filename, the player doesn't work. The player pops up and shows the filename (these characters not correctly shown) but not the ID3-Tag and doesn't start to load the file.
The simple fix is, don't use those characters in folder names. We do everything we can to url encode these parameters to prevent this from happening, the simple fix is to replace those characters with ones the template can read.
I know this workaround but these characters are very common in German language, a lot of artists and even more german songtitles are written with these characters, that are allowed to use for filenames in Windows. I wouldn't like to transribe all characters (Ä to Ae, Ü to Ue, Ö to Oe, ß to ss) in my filenames. It looks odd to me and it would just only be necessary for the use in HFS. Maybe these problems occur to other languages with special characters as well.
I don't think that it should be necessary nowadays to restrict the usage on basic ASCII-Code. I was used to this 20 years ago, when it often even wasn't possible in Germany to write ones own name correctly, when it was for use in a database.
But maybe this isn't a problem of TOG but of HFS? As I notice these german characters are also not correctly shown in your welcome message using %user%.
