Here is how to configure ratings with half-stars similar to MediaMonkey (which equals 10 rating values).
Since almost no font supports the Unicode half-star glyph, I use the ½ glyph instead
In order to get the stars to display for the Playlist font I use Noto Sans CJK HK font
Preferences > Components > Install > (add Quick Tagger)
Preferences > Display > Default User Interface > Colors and Fonts > Fonts > Lists > Playlists
Noto Sans CJK HK
Preferences > Tools > Tagging > Quick Tagger
Field Name (without the quotes) > "Rating"
Values (without the quotes) > "0;1;2;3;4;5;6;7;8;9;10;"
Preferences > Advanced > Display > Properties dialog > Standard fields
Append "Rating=RATING;" (without quotes) to string
Preferences > Display > Default User Interface > Playlist View
Custom Columns > Add new
Name: Rating
Pattern (this should all be one long line): $if(%rating%,$ifequal($meta(rating),10,☆☆☆☆☆,$ifequal($meta(rating),9,☆☆☆☆½,$ifequal($meta(rating),8,☆☆☆☆,$ifequal($meta(rating),7,☆☆☆½,$ifequal($meta(rating),6,☆☆☆,$ifequal($meta(rating),5,☆☆½,$ifequal($meta(rating),4,☆☆,$ifequal($meta(rating),3,☆½,$ifequal($meta(rating),2,☆,$ifequal($meta(rating),1,½,)))))))))),)
Here is a preview of what it looks like: preview
