Developed mostly in Sep 2017, this dictionary includes both pu and commonly used pre-pu vocabulary. Notable for cool design and a search function.

The most widely used font to write linja pona. Includes some pre-built compound glyphs. Each glyph has a Unicode value, making it possible to type them directly without using Latin character ligatures.

linja pona (4) by davidar

A fork of jan Same's linja pona, this version removes pre-built compound glyphs, allowing for every glyph can be turned into a combining character instead. Does not include some features of jan Same's version (Unicode values, recently added glyphs).
