Font metrics (9 pt)

In Windows 8, Chinese Simplified and Chinese Traditional UI fonts conform more closely to Segoe UI metrics in order to provide the same UI look and feel and a consistent user experience with the English UI.

Registry setting

Windows 8 has updated the FontLink chain for East Asian languages and defined at: HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink to support the new fonts for Chinese Simplified and Chinese Traditional:

  • Japanese SKU: Segoe UI links to Meiryo UI
  • Korean SKU: Segoe UI links to Malgun Gothic
  • Chinese Simplified SKU: Segoe UI links to Microsoft YaHei UI
  • Chinese Traditional SKU (including HongKong SKU): Segoe UI links to Microsoft JhengHei UI
Also, all UI fonts link to each other.

Immersive reading

The UI font is also the default font for immersive reading scenarios such as for eBooks. Immersive reading assumes an extended reading time and implies the possibility of breaking up a long text into chapters.

eReading apps may allow the reader to change the font. We also expect more eBook content to be formatted in a designer-specified, often embedded font.

Interactive Text

The UI font is used in applications such as mail or chat where the user is composing the text. These fonts belong to the sans serif font family designed for reading long texts onscreen. It is the default font in Microsoft Outlook, Word, and PowerPoint.

Manifestation

This font change in Windows 8 may impact new and existing applications that call Common Controls and Common File Dialogs without specifying a font.

For example, if there is a CPropertySheet dialog in an MFC application that has no specific font set, then the property sheet will use the new ClearType font. On the other hand, the change doesn’t impact WinForms Controls.

Tests

Test your application to see if any modifications such as specifying the font or resizing controls are needed.
