Luo Shu

Luoshu uses the user-selected Chinese font as the complete base, writing the target glyphs and measurements from the English and numeric fonts into the same composite font, and then mapping it to the system font slot according to the current device's factory font configuration. Chinese, English, and numeric fonts can be selected separately, while avoiding character rollback, font preemption, and direct modification of system partitions.

Starting from v2.3.0, Luoshu uses a completely independent, private self-mounting architecture. The actual font payload is stored in the module's private directory and mounted by Luoshu itself; no meta-modules need to be installed, selected, or configured. Even if other mount-type modules exist on the device, they will not be responsible for Luoshu's font payload.

The module package always includes a native Android management app and also provides a separate APK with the same official signature. The project does not use a WebUI.
