Let me guess. Have you downloaded the image of some Chinese site? Most likely your cue file is encoded in a non-utf-8 encoding. You can convert cue encoding for example to notepad ++ program.
It seems to me that this is GB2312 encoding
Apologies for the sharpness. Maybe in the beginning it is worth making support at the standards level? And then we'll discuss additional features of the parser?
Can make it possible to automatically switch themes in night mode. Make a menu with a choice of themes for night and day mode. For example, "light skin" at day - "dark skin" at night or "custom skin light " at day - "custom skin dark " at night.
In a good way, the theme should include both the dark and light versions in the same package, but alas ...
Early I was glad, AC\DC is an exception in MediaMonkey. Well, I don't think "/" is used anywhere other than id3.
In my entire shopping history, I've only seen these signs (words):",", "feat.","ft.","w/", "with."
No, I'm saying about the ID3 standard. There is already a separation symbol and it does not interfere with writing AC/DC together. I don't know how to implement it, but I have an example where it is already implemented. Based on your comment, I got the impression that you want to ignore the standard
I also want to remind you that the words "feat." , "ft.", "f.", "f /", "with.", "w /", "mix", "remix" can separate authors which can be in title and artist lines.
As far as I know, some meta tags (APEv2, FLAC) can contain multiple values with the same key. And also since ID3v2.3 it is prescribed to separate artists with a "/".
