Обеспечивать хорошие впечатления при чтении является очень важной частью статей Wikimedia. Оформление и главным образом выбор шрифта является основой для лучшей читабельности текста, независимо от устройства, программного обеспечения или родного языка читателя.

Цели и задачи
Исторически сложилось, что наш текущий выбор шрифта, использованного в мобильной версии сайта, для подзаголовков и основного текста строится на стандартых наборах шрифтов. Этот факт приводит к использованию шрифтов "Arial" или "Helvetica" для романских языков на большинстве браузеров. Оба шрифта способствуют доступу информации на всех устройствах, а также являлись бызовым выбором для поддержки широкого спектра пользователей.

Driven by emerging mobile operating systems (OS) and strong growth in markets aside of latin script languages, in the last few years system manufacturers have been introducing new default fonts. These "system fonts" aim to provide better readability and better support for more languages available.

These typefaces


 * deliver a better native experience for readers,
 * improve cross-platform and
 * improve cross-language readability.

Кто увидит эти изменения? We would like to use these system fonts in our selection fonts for the mobile interface presented by Minerva Neue.

Техническая составляющая
You can read more on the technical backgrounds in the Phabricator task.

Proposed system font stack (see discussion on task): This CSS rule will apply the first font in the stack that is available. This is part of open web standards in most browser rendering engines. For example, Roboto is the Android operating system's current default font. None of the first three fonts are on Android systems by default. So, Roboto is selected for rendering the content. Note the code style following our stylelint enforced coding conventions.

To put another way the logic of this CSS rule: User system default > Wikimedia Design choice (Lato) > User operating system desktop only ( Helvetica > Arial) > generic sans-serif With this font stack we're covering at least 89% of mobile browsers outside of generic Helvetica or Arial covered systems in April 2019. The biggest exceptions share-wise are UC Browser Mini and browser sub-summed as “Other” where a big part might still be Chromium/Android based and therefore receive 'Roboto'.

Problem statement
Currently relying on web browser default font choice, which is, out of historical reasons often Arial and Helvetica as least common denominator with the widest language script support. But both fonts date back more than a dozen years.

2019-03-01

 * Wikipedia Portals has been changed to new font stack, with it's variety of language scripts a good, encapsulated place to start.

2019-04-08

 * Mobile web (MinervaNeue) has adopted the new font stack, see for example English or Chinese Wikipedia.

Prior art
There have been a few other web institutions facing similar challenges and taken a similar path:

 * https://css-tricks.com/snippets/css/system-font-stack/

In 2014 there has been a project “Typography refresh”, which had included font stack changes with similar goals but before mobile operating systems penetration were as high. Apart of the prior art projects we have evaluated findings from this project as well to inform our font stack proposed here.
