## What it is
Source Han Mono is an open-source Pan-CJK monospaced typeface family derived from Source Han Sans and Source Code Pro, distributed as a 70-font OpenType/CFF Collection (Super OTC). The repository provides all source files and build instructions using the AFDKO toolchain.

## Use cases
- monospaced font for coding with CJK character support
- Pan-CJK typeface for Japanese, Chinese, and Korean text
- open source font for terminal and code editors
- font that mixes Latin monospace with CJK glyphs
- building OpenType font collections from source

## When to choose
- you need a monospaced font that renders CJK characters consistently with Latin code
- you want an open-source licensed Pan-CJK typeface
- you need to build or customize CJK fonts with AFDKO

## When to avoid
- you need a proportional (non-monospaced) CJK font
- you want a variable font or modern font format like WOFF2
- you cannot handle large font files, as the release ZIP is ~3.25GB

## Facets
- artifact type: dataset
- maturity: maintenance
- function: graphics, developer-tools
- domain: developer-tools, cross-platform
- platform: cross-platform
- tags: font, cjk, monospace, opentype, typography, open-source-fonts, localization
