According to this thread, the scripting line
$if($not(%genre%),$set(genre,***** UNSET *****))
should check if a genre tag is not empty. Otherwise it should fill the genre tag with the UNSET info text.
Im pretty sure this worked fine until Picard 2.3.
In the latest Picard 2.3, this seems not to work anymore. Even if a genre contains “Rock” or “Black Metal”, the text “***** UNSET *****” will be filled in the gerne tag.
Could please someone check this?
If this is not a problem in my environment, I will open a ticket on JIRA.
