Integrated Code 火 is a code-centric font combining Fira Code and Source Han Mono. The duospaced Source™ Han Mono glyphs are twice the width of the monospaced Fira Code glyphs, so you can have consistent alignment.
（机器翻译） Integrated Code 火是一款以代码为核心设计的字体，融合了Fira Code与Source Han Mono的特性。其双倍间距的Source™ Han Mono字符宽度是等宽Fira Code字符的两倍，从而实现统一的代码对齐效果。

You want a Western and Han mono-/duospaced programming font with ligatures and consistent alignment.
The website "Programming Fonts" has previews of hundreds of fonts.
- Fira Code is my favorite code-centric font.
- As of 2026 February 13, the last compiled version was released on 2021 December 6, and I have more recently compiled versions in my fork of Fira Code.

Integrated Code 火
The repository is optimized to work with Visual Studio Code, but that is not required.
-
Clone or fork the repository. (Visual Studio Code instructions.)
-
Install the Python packages in a virtual environment with "uv"; from the folder with the repository, run:
uv sync
- In the names of files and fonts, to avoid confusion, don't use these characters as separators: - (hyphen), – (en dash), — (em dash), or similar characters. For some readers, they can be ambiguous due to 一, which is an ideograph representing "1".
- When preparing files, only make changes in the "workbench" directory. Never change files in directories with glyph and metadata information unless you intend the change to be permanent and universal.

- You contribute to the project?
- Improve configuration management.
- Improve and generalize flow.
- Weights:
- Fira Code has six different weights.
- Source Han Mono has seven different weights.
- Monospaced Noto Sans CJK has two different weights.
- Replace English-language weight names with weight values. "Regular", for example, may become "400".
- Investigate: some monospaced glyphs in Noto Sans CJK are updated replacements for the glyphs in Source Han Mono.
- Investigate: some monospaced glyphs in Source Han Code JP are updated replacements for the glyphs in Source Han Mono.
- Improve font file "packaging", such as:
- One file instead of six.
- Smaller total size.
- Create and use a Vendor ID.
- Create versions for other languages and writing systems.
- If this project were to have a well-designed process for compiling a code-centric font with Latin and simplified Chinese glyphs, it would be relatively easy to expand the process to some other languages and writing systems.
- There seem to be tens of thousands of compatible glyphs in Source Han Mono, Source Han Code JP, and Noto Sans CJK.
- I strongly oppose forcing all writing systems to use Latin characters as the name of the writing system.
- Create one file: updated pan-CJK with Fira Code.
