Media Browser / Media Source integration: Problem with # character in media path

Hi! First of all, I am unsure weather this could be regarded as a feature request or if this topic should be moved to Development, Configuration or even Uncategorized.

I discovered a strange issue about the Media Player panel / Media Source integration when using folder names with a pound sign / hashtag. I am unable to play media from a directory, if it contains a #. This is happening in both Firefox or the HA Companion app on Android.

As I am aware, the # symbol is an allowed character for Linux / Unix paths. If there’s an issue with HA or the integration, it should at least throw an error to the log (I didn’t see anything).

Any input on this?

Thanks!
