Yapiri has now reached its second major version. v1.0 launched in May 2026 as the first complete, usable release of the script. v2.0, delivered in June 2026, brought the UCSUR Plane 15 registration, a refined 45-character inventory, and the Keyman keyboard v2.0. Neither is the destination — they are the first confident steps on a much longer and more beautiful journey.

What v1.0 Delivered (May 2026)

Yapiri v1.0 was the first complete, usable release — not a prototype, not a proof-of-concept, but a fully-formed script with every tool needed to start writing Kokborok. It shipped in May 2026 and was used immediately by early adopters.

Script Specification

The 49 v1.0 characters covered the phonemic inventory of Kokborok: 25 consonants (21 native + 4 extended), 6 vowels, 10 numerals, 5 punctuation marks, 2 diacritics (high tone + reduplication), and a hyphen. v2.0 refined this to 45 characters — dropping f, chh, the reduplication mark, and the hyphen after closer linguistic review, and migrating to the registered UCSUR Plane 15 block U+F1CA0–U+F1CFF. The 23 consonants (21 native + v and z as the only loanword secondaries), 6 vowels, 10 numerals, 5 punctuation marks, and 1 high tone mark now form the complete, stable v2.0 inventory.

The Vision Beyond v1.0

We see Yapiri not just as a script, but as a growing ecosystem that supports the full flourishing of Kokborok in the modern world. Every version will be shaped by real use: by the writers who find what is missing, the teachers who discover what learners need, and the community whose feedback will guide every decision.

"Version 1.0 is a seed planted with love. Each version that follows is how that seed grows toward the light."

The Roadmap Ahead

v2.0 — Delivered (June 2026)
The UCSUR Milestone
  • Codepoints migrated from BMP PUA (U+E000) to UCSUR Plane 15 (U+F1CA0–U+F1CFF) — a registered, conflict-free block confirmed by Rebecca Bettencourt
  • Character inventory refined from 49 to 45 — f, chh, reduplication mark, and hyphen removed after linguistic review
  • Keyman keyboard v2.0 — full Plane 15 codepoint support across desktop and mobile
  • High tone mark redesigned as a native Yapiri combining character (U+F1CD1)
  • All blog posts, specification, and web keyboard updated to v2.0 codepoints
Near term — v2.1
Education & Accessibility
  • A dedicated teaching weight of the font — slightly heavier strokes for classroom and children's materials
  • Mobile-first keyboard layout optimised for small screens and swipe input
  • Yapiri support in more writing applications and operating system text environments
  • Collaboration with Kokborok educators on graded learning materials
  • A handwritten style variant for informal and personal writing
Longer term — v3.0+
The Unicode Path
  • Formal submission to the Unicode Consortium for an official Yapiri block — the path the Chakma script took to reach its permanent home at U+11100
  • Multiple stylistic sets and weights: a display variant, a body text variant, a condensed variant
  • Advanced typographic features for professional publishing and literary typesetting
  • When official encoding arrives: a migration tool already exists that can convert all existing PUA-encoded Yapiri text to the new block by changing a single constant — so nothing written today will become obsolete
Note These milestones are aspirations, not guarantees — the timeline will be shaped by community use, feedback, and the resources available. What they share is a direction: to make Yapiri not only functional but world-class, a script that makes every Tiprasa person proud to write their language.

Community-Driven Development

The future of Yapiri will be shaped by everyone who uses it. The script belongs to the Tiprasa people, and its evolution will reflect their voices. Every bug report, every suggested improvement, every piece of writing shared in Yapiri — all of it contributes to the next version.

If you notice something that could be better — a kern that feels slightly off, a key placement that seems wrong, a character you wish existed — the Community page is where that conversation lives. There is also a poem competition running — the winning entry will be featured on the homepage and become part of the script's living history.

󱲩󱲤󱲩󱲪󱲤󱲷󱲤󱲩 kokborok — in v2.0, and in every version that follows The same word. A better script each time it is written.

The Heart of the Matter

Yapiri v1.0 was built to make something real — not a demonstration, not a concept, but a complete writing system that a person can download today and use to write their language. That is what it is.

What comes next will be shaped by use. By the student who writes her first sentence. By the poet who finds the display variant he needed. By the teacher who asks for a heavier weight for the classroom. By the language that gradually fills the pages of books and the screens of phones with its own face.

The best chapters of Yapiri's story are still to be written. And they will be written — literally — by the Tiprasa people, in the script that was built for them.

The font and keyboard are on the Download page. The primer and chart are there too. Everything you need to start is already in v2.0.
