Let me cite the comment at the top of the pertinent Linux source file, /usr/src/linux-4.13-rc3/drivers/tty/vt/cp437.uni: # # Unicode table for IBM Codepage 437. Note that there are many more # substitutions that could be conceived (for example, thick-line # graphs probably should be replaced with double-line ones, accented # Latin characters should replaced with their nonaccented versions, # and some upper case Greek characters could be replaced by Latin), # however, # I have limited myself to the Unicodes used by the kernel ISO 8859-1, # DEC VT, and IBM CP 437 tables. # It seems to be mainly ASCII, Latin-1, with lots of miscellaneous graphics characters, including the single and double line thingies, sufficient to support mutt, for example. -- Alan Mackenzie (Nuremberg, Germany).
