That's just fine. Copy-and-paste usually works fine. And there are also 
tools called character pickers.

There are many different programming languages, with many different 
limitations and caveats. And of course examples should go into the 
actual implementation code. But they should go into the tests, where 
indeed it's good to have tests for actual UTF-8, not just for hex.
