well i randomly read about unicode having 137 000 individual characters, that is quite a lot.

I hardly doubt there are much / any font supporting the whole 137 000 symbols. Tho if we gether together 1 font which supports all or mesh together multiple fonts to get the full 137 000 symbols we can call it base font. We can than generate wholesome font from any partial one. The base font should be probly un-beveled (or hairlined or skeletoned) – getting only the inner „bezzier“ curve for each symbol.

Then you take comics sans and convert every character to svg or some vector representation. Compare each of its defined symbols with your wholesome base font. Then you can scribble together a snippet generating „font-transformation-function“ or you take „some“ NN and learn it to do the same faster. Then apply the „font-trans-fun“ to every symbol undefined in original comics sans and voila, you have wholesome comics sans with definition for every unicode char.
