Yuki Code is a monospaced font for programmers. It's combined with three fonts:
Nova Mono (for ASCII characters)
Source Han Code JP (for other CJK characters)
Fira Code (for ligatures)
So, this font inherits three fonts features like that:
Beautiful (Nova Mono is the most beautiful monospaced font!)
Japanese Support (Japanese character's width is just double of ASCII's width.)
Ligatures Support (e.g. ==, !=, <=> and more)
