Err yes, both I think. It's doesn't matter much though.

I see various possible ways forward though none is particularly

1. A run-time dependency on libicu, getting libicu to do all the
work, as Boost.Locale does.

2. A run-time dependency on libicu that generates these tables
by interrogating libicu at start-up, and then using Zach's code.

3. Getting users to download the Unicode data files and run the
scripts at Boost compile time.

4. Making an exception to the licensing policy.

5. Removing this from Boost.Text, keeping just the UTFn conversion
code and anything else that doesn't depend on the problematic data files
(as I advocated in my review).

Regards, Phil.
