Defined in:

Overview

Parses ‘Blocks.txt` — one block range per line.

Format (UAX #44):

XXXX..XXXX; Block Name

The ‘id` is the block name with runs of whitespace collapsed to a single underscore. The `name` is preserved verbatim. Per the project rules (CLAUDE.md), block names are NOT otherwise slugified.

‘plane_number` is derived from the high bits of `range_first`.
