A font is more than shapes. The best fonts are intelligent — they know how letters should behave together, adapt to context, and make typing feel effortless and beautiful. Adding OpenType features was one of the most rewarding phases in Yapiri’s development.

What Are OpenType Features?

OpenType is a powerful font format that allows designers to embed smart behaviors inside the font file itself. These include automatic substitutions, alternate letterforms, better spacing, and more.

In simple terms, OpenType turns a static set of glyphs into a living, thinking typeface.

Why OpenType Was Essential for Yapiri

Yapiri is a phonemic script. To make it truly comfortable and professional, we needed features that respected the natural flow of Kokborok:

The Development Process

We began by identifying which behaviors would make typing feel natural. Then came the long process of writing OpenType code (in Feature File format) and testing hundreds of letter combinations.

Some features were straightforward. Others — especially tone mark positioning above different vowel shapes — required dozens of refinements until they felt invisible yet perfect.

"The best OpenType features are the ones users never notice — because everything just feels right."

Key OpenType Features Added

Tone Mark Positioning — The high tone mark now sits gracefully above any vowel.
Reduplication Mark — A clean, consistent mark for repeated syllables.
Stylistic Sets — Alternative forms for users who prefer slightly different aesthetics.
Advanced Kerning — Beautiful spacing between every possible letter pair.

The Joy of Refinement

Seeing the font improve with each update was deeply satisfying. Sentences that once looked slightly awkward now flowed with natural elegance. Poetry looked more beautiful. Children’s books became easier to read.

The Heart of the Matter

Adding OpenType features was an act of care. It showed respect for the language and for the people who would use it. We didn’t want Yapiri to be just usable — we wanted it to feel premium, modern, and deeply satisfying.

Every smart feature we added was a quiet promise: your language deserves the best tools available. Yapiri is not only a script for today, but one built with ambition for the future.

The journey continues. More features will come. But today, Yapiri is not just a font — it is a complete, intelligent writing system ready to carry the voice of the Tiprasa people into the digital age.
