For Korean, the font is different.

I don't set a custom font and use the default font in Ghostty. However, when working with Hangul, the font looks strange. How can I resolve this issue? I want a Hangul font similar to iTerm. However, it seems that Hangul is being rendered in [PCMyungjo] in Ghostty.

iterm

ghostty

Ghostty's default font, JetBrains Mono, does not contain any CJK characters, and thus it falls back to a CJK font when rendering them. If it's not possible to know which font iTerm2 uses, then the simplest way to get both to look the same is to explicitly use a CJK font that also contains monospace characters for both terminals (e.g. Sarasa Gothic). You can also tell Ghostty to use a different font only for CJK characters only through the font-codepoint-map config option, while other characters use JetBrains Mono (or another fallback font)

Since our builtin doesn't have CJK, it's simpler than that: you can provide a second font-family as an explicit fallback font. That's the recommended approach to ensure you always get the font you want.

Thank you for your response!

By downloading a CJK-supported font and setting it as a fallback font like this:

font-family = "JetBrains Mono"
font-family = "Noto Sans CJK KR"

It now displays as intended!
