This structure contains information identifying the code pages and Unicode subranges for which a specified font provides glyphs.

typedef struct tagFONTSIGNATURE {
DWORD fsUsb[4];
DWORD fsCsb [2];


  • fsUsb
    Specifies 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
    Specifies a 64-bit code-page bitfield (CPB) that identifies a specific character set or code page. Code pages are in the lower 32 bits of this bitfield. The high 32 are used for non-Windows code pages.


The graphics device interface (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.
