"""Read entities.json (WHATWG HTML named character references) and generate
|
||
|
|
WingEntities.cpp with a lookup table of { "name", codepoint } rows.
|
||
|
|
|
||
|
|
Rules:
|
||
|
|
- Only entries whose key ends with ';' (skip legacy semicolon-less forms).
|
||
|
|
- Only entries with exactly one codepoint.
|
||
|
|
- Codepoint must be <= 0xFFFF (Unreal uses 16-bit TCHAR).
