That makes sense; the trie I use to store the derived properties for all of
Unicode 8.0.0 is 23 KB in memory (it would be a bit bigger over the wire;
though there's also room for improvement there). This seems reasonable at
first glance, however, a similar structure for normalization ends up being
53 KB, and the one for width mapping is 11 KB; I suppose it begins to add
up quickly if you're on a slow connection

I suppose it comes down to a trade off between complexity and portability;
I'm not sure which makes the most sense in this case.


Best,

Sam
