JSI Tip 1110. How do I adjust Windows NT to handle very large character sets (fonts)?

If you regularly manipulate many very (very) large character sets, you may wish to tune the FontCache.

Note: Altering the FontCache can significantly influence the amount of memory used by Windows NT.

The FontCache key is located at:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\FontCache

Note: The following Value Names are all type REG_DWORD entries and have a range of 0x0 - 0xFFFFFFFF KiloBytes.

 Value Name   Default (KB)   D e s c r i p t i o n 
 MaxSize   0x80 (128)   Maximum amount of address space reserved for each font cache. 
 MinIncrSize   0x4   Mimimum amount of memory committed each time the system increases the size of a font cache. 
 MinInitSize   0x4   Minimum amount of memory initially committed for each font cache when the cache is allocated.
