Windows 10 converges the Windows platform for use across multiple device categories. The description above of previous releases applies to Windows Client (desktop) and Server editions. This section on Windows 10 covers all Windows 10 editions, including Desktop, Server and Mobile.
All Windows 10 editions support the same set of scripts. In addition to the scripts supported in earlier Windows releases, Windows 10 adds support for several additional, historic scripts. These are supported using the new Segoe UI Historic font:
|Brahmi||Indian subcontinent||Segoe UI Historic||Historic|
|Carian||Europe||Segoe UI Historic||Historic|
|Cypriot||Europe||Segoe UI Historic||Historic|
|Egyptian Hieroglyphs||Middle East||Segoe UI Historic||Historic|
|Imperial Aramaic||Middle East||Segoe UI Historic||Historic|
|Inscriptional Pahlavi||Middle East||Segoe UI Historic||Historic|
|Inscriptional Parthian||Middle East||Segoe UI Historic||Historic|
|Kharoshthi||Indian subcontinent||Segoe UI Historic||Historic|
|Lycian||Europe||Segoe UI Historic||Historic|
|Lydian||Europie||Segoe UI Historic||Historic|
|Phoenician||Middle East||Segoe UI Historic||Historic|
|Old Persian Cuneiform||Middle East||Segoe UI Historic||Historic|
|Old South Arabian||Middle East||Segoe UI Historic||Historic|
|Shavian||Europe||Segoe UI Historic||English phonetic writing|
|Sumero-Akkadian Cuneiform||Middle East||Segoe UI Historic||Historic|
|Ugaritic Cuneiform||Middle East||Segoe UI Historic||Historic|
Certain other historic scripts were supported in earlier versions in the Segoe UI Symbol font. In order to avoid duplication, the following scripts have been removed from Segoe UI Symbol and included in Segoe UI Historic:
- Meroitic Cursive
- Old Italic
In Windows 8.1, the Meiryo UI font family was used for Japanese text in the Windows user interface. On Windows Phone 8.1, the popular Yu Gothic font was used for Japanese. In Windows 10, the user interface font family for Japanese has changed to Yu Gothic UI for all editions. In order to make Yu Gothic UI perform as intended in Windows UI, Yu Gothic UI is adapted from Yu Gothic with certain metric and character width modifications as well as alternate glyphs for Latin characters. For non-UI content, the Yu Gothic fonts are still included. For optimal readability, the OpenType “palt” feature (proportional alternate widths) should be enabled for text formatted with Yu Gothic.
Another change pertaining to user interface fonts is that a semilight weight has been added to the Malgun Gothic family. Otherwise, user interface fonts for other languages are the same as in Windows 8.1.
In Windows 8 and Windows 8.1, private-use-characters in the Segoe UI Symbol font were used for user interface iconography. In Windows 10, the Segoe MDL2 Assets font has been added to provide newer iconography.
An important development in Windows 10 is the Universal Windows Platform (UWP): a converged app platform allowing a developer to create a single app that can run on all Windows devices. Windows fonts are one aspect of this convergence: Windows 10 introduces a recommended UWP font set that is common across all editions that support UWP, including Desktop, Server, Mobile and Xbox.
For information regarding which fonts are included in the recommended UWP font set, complete details are provided in Guidelines for fonts. One important point to note is that the recommended font set does not include all of the weights for certain font families. In particular, due to the large size of East Asian fonts, only the regular weight of East Asian font families are included in the recommended font set.
A number of additional fonts are available for Desktop and Server, including all other fonts from previous releases. However, not all of these are pre-installed by default in all images. In order to make disk usage and font choices more relevant to users according the languages that they use, a number of fonts have been moved into optional on-demand packages. These packages are designed around the different scripts that fonts are primarily intended to support, and most are installed automatically by Windows Update when the associated languages are enabled in language settings (for example, by enabling a keyboard).
Any of these optional font packages can also be installed manually by any user in Settings. One package is not triggered automatically but can be added by enabling it in Settings. To add font packages manually, go to Settings > System > Installed apps > Manage optional features.
The following are the optional font packages that are automatically installed based on changes to language settings:
- Arabic Script Supplemental Fonts
- Bangla Script Supplemental Fonts
- Canadian Aboriginal Syllabics Supplemental Fonts
- Cherokee Supplemental Fonts
- Chinese (Simplified) Supplemental Fonts
- Chinese (Traditional) Supplemental Fonts
- Devanagari Supplemental Fonts
- Ethiopic Supplemental Fonts
- Gujarati Supplemental Fonts
- Gurmukhi Supplemental Fonts
- Hebrew Supplemental Fonts
- Japanese Supplemental Fonts
- Khmer Supplemental Fonts
- Kannada Supplemental Fonts
- Korean Supplemental Fonts
- Lao Supplemental Fonts
- Malayalam Supplemental Fonts
- Odia Supplemental Fonts
- Sinhala Supplemental Fonts
- Syriac Supplemental Fonts
- Tamil Supplemental Fonts
- Telugu Supplemental Fonts
- Thai Supplemental Fonts
The following optional font package must be installed manually:
- Pan-European Supplemental Fonts
Note: These optional packages are for Desktop and Server editions only.
Moving these fonts into optional packages provides over 220 MB of disk savings for users who don’t require these fonts.
Another significant development in Windows 10 from an international perspective is the introduction of a new complex-script shaping engine — the Universal Shaping Engine — that allows any complex script in Unicode 7.0 to be shaped correctly even if the script is not yet supported by a system-provided font. Users have the option to install a suitable OpenType font to get correct shaping behavior for any script in Unicode 7.0.
Note: While the Windows platform is able to support display of additional Unicode 7.0 scripts using non-system fonts, this doesn’t not guarantee that this will work in all apps. In particular, apps that do their own low-level text-display processing may not display a script correctly unless they were explicitly designed to support that script, even though they call platform APIs that use the universal shaping engine. Also note that platform frameworks will not provide font fallback behavior using non-system fonts.
The following complex scripts in Unicode 7.0 are supported in the Universal Shaping Engine.
Balinese, Batak, Brahmi, Buginese, Buhid, Chakma, Cham, Duployan, Egyptian Hieroglyphs, Grantha, Hanunoo, Javanese, Kaithi, Kayah Li, Kharoshthi, Khojki, Khudawadi, Lepcha, Limbu, Mahajani, Mandaic, Manichaean, Meitei Mayek, Modi, Mongolian, N’Ko, Pahawh Hmong, Phags-pa, Psalter Pahlavi, Rejang, Saurashtra, Sharada, Siddham, Sinhala, Sundanese, Syloti Nagri, Tagalog, Tagbanwa, Tai Le, Tai Tham, Tai Viet, Takri, Tibetan, Tifinagh, Tirhuta
Other scripts in Unicode 7.0 either are supported in other shaping engines or do not require complex script handling.
