Overview

Parses ‘CJKRadicals.txt` — KangXi radical → CJK radical ideograph → canonical ideograph mapping.

Format (UAX #44):

radical_number; cjk_radical; ideograph

‘cjk_radical` and `ideograph` are either a single hex codepoint (`2F00`) or a range in the form `XXXX..YYYY`. Range rows are expanded to one CjkRadical per codepoint.

Coordinator merges each row into the relevant CodePoint.
