feat: support multi-region CJK fonts (KR, SC, JP) using native system fonts #8
Conversation

Thanks for this fix! The implementation looks solid. One concern: the Noto Sans KR font adds ~15.7 MB to the binary size. Would you be open to trying a system font fallback approach first? For example, on most systems there are already CJK fonts installed:
We could try those as fallbacks before bundling a font. If no system font is available, THEN we could consider bundling a subset or the full font. What do you think? |

introduced the font-kit library to enable direct loading of local fonts installed in the OS (e.g. Apple SD Gothic Neo, Malgun Gothic) at runtime. |

This is fantastic! Thank you for reworking the PR to use system fonts The multi-region support (Korean, Chinese, Japanese) is a great bonus, and the implementation looks solid with proper fallback handling. One small thing: there's a duplicate test_korean.md in the root directory (the one in test_md/ folder is probably the intended location). Could you remove the root-level one, or should I do it after merge? |
