//
//  This allows Quickbooks v4 & v5 to use their OCR-A.TTF font right after they
//  install.  At the end of installation on both versions, you are asked if you
//  want to "restart" windows. If you click OK it logs you off of NT5, but does
//  *not* reboot the system -- which the app is counting on to cause the OCR-A 
//  font to be loaded. The result on W2K is that whenever the app uses the OCR-A
//  font, it will get mapped to wingdings instead.
//
//  This is further complicated by the fact that the font file OCR-A.TTF doesn't
//  specify the charset in the header.  On Win3.1, Win95, & pre-NT5, unspecified
//  charset's got mapped to the SYMBOL_CHARSET - therefore, Quickbooks specifies
//  SYMBOL_CHARSET in its LOGFONT struct to accomodate this.  (OCR-A apparently
//  is licenced from Monotype Typography, Ltd. which presumably is why Intuit
//  didn't fix the header issue in the font file).
//
//  This changed on Win98 and W2K, unspecified charset's now get mapped to the
//  DEFAULT_CHARSET.  This was done so these fonts will always map to a default 
//  localized font that will always be readable. Hence, the hack where we change
//  the charset from SYMBOL_CHARSET to DEFAULT_CHARSET in the LOGFONT struct.
//
//  On v4, the install program copies OCR-A.FOT & OCR-A.TTF to the SYSTEM dir.  
//  Once you "restart" (not reboot) the system & log back on, the OCR-A font is
//  added to the registry (as OCR-A.FOT) but the font files are still in the 
//  SYSTEM dir.  Rebooting causes the fonts files to be moved to the FONTS dir,
//  the registry entry is changed to OCR-A.TTF. (done by the "Font Sweeper")
//
//  On v5, the install program copies the .ttf & .fot files to the FONTS dir
//  but again, counts on the reboot to cause the fonts to be loaded.  It puts 
//  correct registry entry (OCR-A.TTF) in the registry fonts section.
//
//  The result of all this is:
//  For either version of the app, without the charset hack, you will always get
//  a wingding font instead of OCR-A.  With the charset hack, you will get a
//  readable font, such as Arial, until you reboot -- after which you will get
//  OCR-A for v5 but Arial for v4. With this function (in conjunction with the 
//  charset hack) both version will always get OCR-A with or without rebooting.
//
//  This function explicitly loads the OCR-A from the font files located in 
//  either the FONTS dir or the SYSTEM dir.
