使用场景 · Use case

I would like to suggest adding Korean language support to the ZCode UI. Currently, the i18n implementation on ZCode is incomplete or unsmooth, which makes the user experience slightly disappointing for Korean users when navigating the interface.

建议方案 · Proposal

• Provide an official localization for the ZCode UI.
• Optimize the general multi-language (i18n) rendering so that text layouts flow smoothly without any formatting breaks.

预期价值 · Expected value

It will significantly lower the entry barrier for Korean developers and improve the overall day-to-day workflow comfort.
