Comprehensive support for Unicode, with over 20 scripts providing layout and rendering of every language supported in Windows. DirectWrite supports measuring, drawing, and hit-testing of multi-format text. Supported Unicode features include BIDI, line breaking, surrogates, UVS, language-guided script itemization, number substitution, and glyph shaping.
Sub-pixel ClearType text rendering with bi-directional antialiasing which can interoperate with GDI/GDI+, Direct2D/Direct3D and any application-specific technology. When using with Direct2D, text rendering can be hardware-accelerated or can use WARP software rasterizer when hardware acceleration is not available.
Supports advanced typographic features of OpenType, such as stylistic alternates and swashes, which were never supported in GDI and WinForms.
Provides a low-level glyph rendering API for those who employ proprietary text layout and Unicode-to-glyph processing.
