Discussion

Now that we got rid of the left-curly-brace in regex problem, Karl Williamson has some ideas on reusing it. Think \w{Latin|Greek} , for example.

Karl Williamson has mentioned script runs before and now raised the topic again with more information after we fleshed it out during the core hackathon.

Karl is also working on optimizing the handling of UTF-8.

Philip R. Brenan asked about introducing Unicode characters as operators.

Zefram followed up with thoughts on source encoding.
