The actual information that UTF *has* is which natural number corresponds to which glyph. Ask about this.
Whom
My apologies, clearly it was another person who wanted to ask (or already asked) the boost lawyers and the UTF consortium lawyers.
should I ask what?
If this "number" ↔ "glyph" correspondence can be used by boost on the terms of boost license.
The license applies not to the abstract coding of glyphs or characters but to the data files published by Unicode Inc. that describe this. It is these files Zach translates into bits of Boost.Text code, which is then claimed to be not covered by Unicode Inc. license. The important difference is that (a) Zach is using a material document that is licenseable (as opposed to abstract facts or numbers, which are not) as a source and (b) the result of translation preserves the original information in some meaningful amount (as opposed to e.g. applying a hash function or `wc`, which does not).
