How to Use Converted Fonts

Font Converter, upload a TTF/OTF file.
Select the desired Unicode ranges (Korean, Chinese, Japanese, etc.).
Set the font size and bit depth, then convert.
Copy the converted .epdfont file to /.crosspoint/fonts/ on the SD card or to the root /fonts/ folder.
On the device, choose the font in Settings > Font Settings.

Supported Font Formats and Limitations

Supported formats: TTF, OTF, WOFF, WOFF2

Unsupported fonts:

Variable Fonts - the variable font interface is not currently implemented in FreeType WASM.
Color Fonts / Emoji - color-layer fonts render in monochrome only.
Bitmap-only fonts - pure bitmap fonts without scalable outlines cannot be converted.

Most common Korean fonts (Nanum Gothic, Malgun Gothic, Noto Sans CJK, etc.) convert without issue.

Advanced: Python Conversion

If you need more Unicode ranges or finer control, you can use a Python script.

Requirements

Python 3.8 or later
freetype-py library

Installation

pip install freetype-py
