Note that the EGA-compatible text modes (which use an 8x14 font) and graphic modes 10 and F use
a 16 dot high font, with the bottom two lines truncated, in the absence of the 8x14 Font TSR
(TSRFONT). This creates some errors in displaying characters with descenders, but does not restrict
operation of programs using these modes. In text modes using the 8x14 font, the characters "g," "j,"
"p," "q," "y," and "ÿ" are truncated using a middle and bottom line algorithm to avoid truncation of
descenders. For compatibility with some DOS applications that use the 8x14 font, the TSRFONT
utility should be used. Applications such as DOSSHELL in Graphics 25 or 34 line display modes
require the TSRFONT utility to be loaded.
