wcwidth-o1/dist/combining.d.ts

Unicode text width calculation (wcwidth/wcswidth) for Node.js and TypeScript, optimized to O(1), based on Markus Kuhn's reference.

/**
 * Bitset accessor for combining/zero-width characters (Unicode 17.0.0).
 *
 * - Uses `combiningMap` for sparse bitset lookups.
 * - Returns 0 if a block has no zero-width characters, or -1 for carve-outs.
 *
 * @param idx Codepoint block index (ucs >> 5)
 * @returns 32-bit mask of zero-width characters for this block, or -1
