SD Card Fonts

CrossPoint supports loading additional fonts from the SD card, including fonts with extended Unicode coverage (CJK, Cyrillic, Greek, etc.).

Installing Fonts

There are three ways to install fonts:

Option 1: Download from device (recommended)

Connect your CrossPoint reader to WiFi
Go to Settings > System > Manage Fonts
Browse available font families and tap to download
Downloaded fonts appear immediately in Settings > Reader > Font Family

Option 2: Upload via web browser

Connect your CrossPoint reader to WiFi
Open the web interface in your browser (shown on the WiFi screen)
Navigate to the Fonts tab
Upload .cpfont files using the upload form

Option 3: Manual SD card copy

Download font files from the crosspoint-fonts repository
Copy font family folders to one of two locations on your SD card:
- /.fonts/ — hidden directory (preferred; keeps the SD root tidy when mounted on a desktop)
- /fonts/ — visible directory (use this if your OS hides dot-files and you'd rather see the folder in your file manager)
Both roots are always scanned at boot and the results are merged: a family installed in /fonts/ shows up even when /.fonts/ also exists, and vice versa. The two roots only collide if the same family name appears in both — in that case the copy in /.fonts/ wins and the duplicate in /fonts/ is ignored.
```
SD Card Root/
├── .fonts/                     ← Hidden root (preferred)
│   └── Literata/
│       ├── Literata_12.cpfont
│       ├── Literata_14.cpfont
│       ├── Literata_16.cpfont
│       └── Literata_18.cpfont
└── fonts/                      ← Visible root (equally valid)
    └── Merriweather/
        ├── Merriweather_12.cpfont
        └── ...
```
Insert the SD card and power on your CrossPoint reader
