    Mozc

    Mozc

    Mozc - a Japanese Input Method Editor designed for multi-platform

    Mozc is an open source Japanese Input Method Editor (IME) developed by Google, designed to provide Japanese text input across multiple operating systems including Android, macOS, Windows, GNU/Linux, and Chromium OS. The project originated as a subset of Google Japanese Input, released publicly under the BSD 3-Clause license for community use and development. Mozc offers core IME functionality such as text conversion, prediction, and dictionary-based input, enabling users to efficiently type and edit Japanese text. While Mozc shares much of its codebase with Google’s internal IME, it operates as an independent open source project without official support, guarantees, or stable release cycles. Developers can build Mozc from source for their preferred platform, and the repository includes detailed build instructions for Android, Linux, macOS, and Windows environments.

    HarfBuzz

    HarfBuzz

    Open source text shaping engine

    HarfBuzz is an open source text-shaping engine with a C API that turns fonts and strings of character codes into a form that is correctly arranged for the corresponding language and writing system. This is essentially the process of text shaping: translating a string of character codes into a properly arranged sequence of glyphs that can be rendered onto a screen or into final output form for inclusion in a document. This shaping depends on a number of factors: the input string, the active font, the script (or writing system) of the string, and the string's language. Various font formats have their own set of standard text-shaping rules. With Harfbuzz, you can properly shape all the major writing systems. HarfBuzz is cross-platform and supports all major software platforms and font formats.
