I think what you're describing is one of the "Unicode Transformation
Formats" (UTF-8) rather than Unicode per se, or the Universal Coded
Character Set. But I'm sure our studies will cover all the nuances.

Sounds good, I'll reply on-list as things come up.

Yeah, that sounds fun! Some ideas:
* A filter to normalize text (like the apostrophe thing we were talking
* A tool to detect tricky characters in a file. So you could pipe urls
into it from a mutt message to scan for possible phishing attacks that
are designed to mimic a reputable domain
* A filter to go the other way: disguise a string. Use weird, slightly
off characters in the string to fool naive search engines, making the
text hard to find
* Unicode-enabled word counter which properly segments words in any
* Grep that works modulo diacritics, so I could search for "eclat" and

It's interesting because that apostrophe is the one the unicode
committee recommends, so in this case Apple is going with the standards.
But in general yeah those big companies do like to meddle.
