Adding a 14 KB Kanji Table to a JavaScript QR Generator

说明与用途

将 14 KB Kanji 表集成到 JavaScript QR 生成器中，实现了本地 Kanji 模式编码，节省最多 21 位，并使用动态规划选择最佳编码模式。

问题

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

结果

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.

工作流

• 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.

证据

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

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

来源

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