Enabling EUDC (Windows CE 5.0)
Although Windows CE defines thousands of characters, you may need to define your own set of characters. You can use end-user-defined characters (EUDC) to define a character or glyph for a device. For example, you can use EUDC to represent proper names that use Asian characters.
To enable EUDC, create subkeys to associate a font with an EUDC set. You can create these subkeys under the HKEY_CURRENT_USER\Eudc registry key.
To install a system-wide EUDC font, modify the SystemDefaultEUDCFont=\windows\xxxx.tte entry. The following example shows how to associate the system default EUDC font with all fonts that do not have any other EUDC associations.
SystemDefaultEUDCFont=\windows\eudc.tte
To set the size of the glyph cache, use the HKEY_LOCAL_MACHINE\System\Gdi\Glyphcache registry key. This key is read only when the OS boots.
The following example shows how to set the size of the glyph cache.
HKEY_LOCAL_MACHINE\System\Gdi\Glyphcache
"limit"=DWORD:x
The value specified for the limit is the size in bytes of the glyph cache per realized font. This number is automatically multiplied by 4 for antialiased fonts.
A realized font is any unique combination of font, height, weight, and effects (for example, outline or emboss). A font is realized the first time an application uses it for drawing, and is unrealized when the application deletes the HFONT.
