This seems like a bit of a hodgepodge; I'm not sure all these character sets were supported back in the DOS days and some of the character, like the runic ones, seem too big. It would be nice to know where these are all sourced from.
EDIT: without the extra letter spacing added in the character samples, you can see how some of the wider characters run into their neighbors:
javascript:document.styleSheets[0].insertRule('.character-list { letter-spacing: normal !important }')
