[yxswgwqe] Use Unicode as little as possible

Unicode, by its charter, provides "as much as possible", the union of all existing character sets and symbols.  That doesn't mean you should use it as much as possible.  In fact, you should be conservative in how much of it you use, using the minimum necessary to accomplish your communication goal.  The recipient might not have as much Unicode support as you were hoping, and a channel using lots of Unicode is vulnerable to attacks like homograph attacks.

This is kind of a variation on, be liberal in what you accept, be conservative in what you do.
