Wrong character glyphs for available fonts (amiga mode) of the DOS version
The glyphs of characters 220 and 221 (located in the file fontdata.h) should be 'œ' and 'Œ' instead of '½' and '¼', according to the DM4 definition.
[ main i p;
p = 3;
print " ";
for (i=155 : i<252 : i++) {
print (char) i;
++p;
p = p & 7;
if(p == 0) new_line;
}
];
Under Dosbox:
frotz -d5 -g1 glyphs.z5
There are many more wrong character glyphs with a fixed-width font since, in this case, the system font is used (related to this issue).
frotz -d5 -g0 glyphs.z5
