 When VioSetFont is issued, the current code page is reset. If [[VioGetCp]] is subsequently issued, the error code ERROR_VIO_USER_FONT is returned. Return code, ERROR_VIO_USER_FONT represents a warning. It indicates that although the font could not be loaded into the adapter using the current mode, the font was saved as part of a special user font code page for use with a later [[VioSetMode]]. Successfully setting a user font sets the special user font code page, just as if a code page of -1 was specified using [[VioSetCp]].

 The special code page is used in the same way as those code pages specified on the CODEPAGE = statement in CONFIG.SYS.
