Guide
Vertical text, set the way it’s read.
Vertical Japanese and Chinese have rules of their own: lines run top to bottom, columns advance right to left, and ruby sits beside its characters. Tomelet sets 縦書き, ruby and the right-to-left column progression with the same engine that lays out every other book.
Part of the free reader — no separate mode to switch on.
How vertical writing works
Vertical writing has a grammar of its own. Lines stack from top to bottom, columns advance from right to left, and ruby annotations sit alongside the characters they describe.
Get each of those details right and the page reads naturally for the people it was written for. Tomelet sets every one of them with the care of the printed edition.
What correct looks like
Line and column flow
Text reads top to bottom, and columns progress from right to left, so the book turns the way it should.
Ruby (furigana)
Pronunciation guides stay attached to their characters, clear and easy to read.
Right-to-left too
The same engine lays out Arabic and Hebrew right to left, and sorts each language’s text by its own rules.
One engine for every script
Vertical Japanese and Chinese, ruby and right-to-left scripts are handled by Tomelet’s one reading engine — the same one that keeps a publisher’s fonts and paginates every other book — so every script gets the same care.
FAQ
Questions & answers
Does Tomelet support ruby (furigana)?
Yes. Ruby annotations stay attached to their base characters in both vertical and horizontal text.
Can it read vertical Chinese as well as Japanese?
Yes. Vertical writing with right-to-left column progression is rendered for both, from the same engine.
What about right-to-left languages like Arabic?
Right-to-left layout and per-language sorting are handled by the same engine, so Arabic and Hebrew books read correctly too.
