The sheer amount of these CJK characters in existence lead to massive font file sizes.

存在的这些 CJK 字符的绝对数量导致了巨大的字体文件大小。

From what I found, other regions that use CJK characters don't exhibit the same design patterns as Japan.

据我发现，其他使用 CJK 字符的地区并没有表现出与日本相同的设计模式。

These are all factors that could realistically cause design differences between regions that use CJK characters and the rest of the world, except it doesn't.

这些因素实际上都可能导致使用 CJK 字符的地区与世界其他地区之间的设计差异，但事实并非如此。
