This commit adds the directory `/core/assets/UCD/`. This directory
contains three files; `PropList.txt`, `UnicodeData.txt`, and `license.txt`.
These files are from the Unicode Database (UCD). The first two are used to
generate tables for `core/unicode`. The third is the license that
covers the files that make up the UCD.
These files are from Unicode version 17.0.0. The latest versions may be
found ad [ucd](https://www.unicode.org/Public/UCD/latest/ucd/).
A from-scratch XML implementation, loosely modeled on the [spec](https://www.w3.org/TR/2006/REC-xml11-20060816).
Features:
- Supports enough of the XML 1.0/1.1 spec to handle the 99.9% of XML documents in common current usage.
- Simple to understand and use. Small.
Caveats:
- We do NOT support HTML in this package, as that may or may not be valid XML.
If it works, great. If it doesn't, that's not considered a bug.
- We do NOT support UTF-16. If you have a UTF-16 XML file, please convert it to UTF-8 first. Also, our condolences.
- <[!ELEMENT and <[!ATTLIST are not supported, and will be either ignored or return an error depending on the parser options.
TODO:
- Optional CDATA unboxing.
- Optional `>`, ` `, ` ` and other escape substitution in tag bodies.
- Test suite
MAYBE:
- XML writer?
- Serialize/deserialize Odin types?
