I think the Japanese font used on Android might be doing something like this! Look at this screenshot: https://ibb.co/hUAgWw https://ibb.co/hUAgWw Upper line - complex kanji, Lower line - its components. When you look at the complex kanji on the upper line, some of its components look unnaturally stretched, as if they were automatically scaled instead of being drawn by hand. So I'm guessing the design is at least semi-automated. (It's common for kanji like 日 and 雨 to have slight visual differences when used as components – the tiny 'legs' 日 has are missing in 曇 and 温, at least in the font I have. But it still looks like they just have a few variants of each character that are reused)
