Jetendard is a coding font project that combines two existing fonts into one. It takes JetBrainsMono Nerd Font Mono, a popular monospace font used in code editors and terminals that already includes programming ligatures and icon symbols, and swaps in Korean characters from a font called Pretendard. The Korean glyphs are enlarged slightly so they sit more comfortably next to the Latin letters, which the author says makes Korean text read more clearly and feel less cramped when mixed with English code and comments. The project is closely based on an earlier project called Yeomil Mono, which combined a different Latin font with Pretendard. Jetendard reuses much of that project's approach but swaps in JetBrainsMono as the Latin base font and applies a slightly different scaling to the Korean characters. Building the font requires a Python environment manager called uv. Running a short sequence of setup and build commands downloads the source fonts and produces a full family of sixteen font variants, covering weights from Thin to ExtraBold in both upright and italic styles, in TTF, OTF, and web font formats ready to install or use on a website. Because Pretendard does not offer true italic versions of its Korean characters, the italic variants of Jetendard use italic Latin letters paired with upright Korean characters, even though the font files are still labeled as italic. The project only uses one specific version of JetBrainsMono, the one that already has ligatures and icon symbols built in, so it does not need any extra patching step. This is a tool for developers, especially those who write code with Korean comments or work in editors and terminals that display both English and Korean text, and want the two to look visually balanced together. It is released under the SIL Open Font License, a license commonly used for free fonts.
