Resolve a Unicode block name (loose matching) to its range, size, count of assigned characters and a small sample. An unknown block is a successful `found:false`. This is a Unicode Character Database block — not a blockchain block.

Resolve a single code point (given as 'char' or 'codepoint') to its name, general category, block, script and plane. Provide exactly one of the two inputs.

Reverse lookup: resolve a Unicode character name (e.g. 'SNOWMAN', 'CJK UNIFIED IDEOGRAPH-4E2D', 'HANGUL SYLLABLE GA') to its code point. Loose whitespace/case matching. An unknown name is a successful `found:false`.

Resolve a Unicode script name (loose matching) to its code point ranges, total size and a small sample. An unknown script is a successful `found:false`.
