"double the amount of information in one character as you can in many other languages"

But don't Japanese, Korean, etc. also need twice the number of bits per character as the standard Latin character set to encode them?

Remember the tweet character limit was originally set to allow it to fit into one SMS which allows 140 characters for 8-bit Latin sets, 70 characters if you need to extend up to 16-bits.
