- Support astral Unicode characters. (#174)
66

77
Unicode characters from outside of the Basic Multilingual Plane can now
88
be used in values of `TextElements` and `StringLiterals`. This means all
99
characters in the U+10000 to U+10FFFF range. 🎉

11+
- Don't store the `-` sigil in `Identifiers` of `Terms`. (#142)
12+
13+
The `-` sigil is no longer part of the term's `Identifier`. This is now
14+
consistent with how `Identifiers` of variables don't include the `$`
15+
sigil either.
