 * Key features:
 * - Myriad-based (萬, 億) grouping - 4 digits
 * - Formal (financial) vs common numerals
 * - Zero insertion for skipped positions
 * - No word separators (concatenated format)
 *
 * Differences from Simplified:
 * - Different character forms (e.g., 負/负, 點/点, 億/亿, 萬/万)
 * - Some formal numerals differ (參/叁, 貳/贰, 陸/陆)
