FONTSIGNATURE
The FONTSIGNATURE structure contains information identifying the code-pages and Unicode
subranges for which a given font provides glyphs.
typedef struct tagFONTSIGNATURE {
DWORD fsUsb[4];
DWORD fsCsb[2];
} FONTSIGNATURE;
Members
fsUsb
A 128-bit Unicode subset bitfield (USB) identifying up to 126 Unicode
subranges. Each bit, except the two most significant bits, represents a single
subrange. The most significant bit is always 1 and identifies the bitfield as a font
signature; the second most significant bit is reserved and must be 0. Unicode
subranges are numbered in accordance with the ISO 10646 standard.
fsCsb
A 64-bit, code-page bitfield (CPB) that identifies a specific character set or
code-page. Windows code-pages are in the lower 32 bits of this bitfield. The
high 32 are used for non-Windows code-pages. For more information, see Code-Page Bitfields.
Remarks
GDI relies on Windows code-pages fitting within a 32-bit value. Furthermore,
the highest two bits within this value are reserved for GDI internal use and may
not be assigned to code-pages.
