Adding a 14 KB Kanji Table to a JavaScript QR Generator

Описание и применение

Встроенный 14 КБ таблица Kanji позволяет JavaScript‑генератору QR кодов кодировать японские символы без внешних пакетов, экономя до 21 бита за сегмент и автоматически переключая режимы для оптимальной эффективности.

Задача

Integrate Kanji support into a JavaScript QR generator without external encoding packages.

Результат

The integrated Kanji table allows the generator to encode Kanji characters natively, saving up to 21 bits per segment and enabling dynamic mode switching for optimal bit usage.

Рабочий процесс

• 1. Reduce Kanji lookup table size by 36% using dynamic programming.
• 2. Integrate the compressed table into datalog/qrcode-generator.
• 3. Update segment optimizer to use the new table for Kanji mode.
• 4. Test encoding with mixed Kanji, spaces, Greek, and Cyrillic characters.
• 5. Verify bit savings and correct segment selection.

Доказательства

That table is now integrated into datalog/qrcode-generator. It provides the character mapping needed for Kanji mode without an external encoding package.

Источник

Splitting the text saves 21 bits, even after paying for three segment headers.

Источник

The optimizer uses dynamic programming with four modes: Numeric, Alphanumeric, Byte, and Kanji.
