You have probably already tested this, but in Windows text editors (even
Word) it simply displays as a box. In MS-DOS, the TYPE command displays the
glyph associated with U+2302 HOUSE (a.k.a. INVERTED HOME PLATE). I don't
know if this would be different using the ANSI X3.64 emulator (ANSI.SYS).
Actually, I wasn't expecting this. I tested a file containing the text
"ABC*DEF" (where * = DEL) and expected that at least one process would
display "ABDEF" where the DEL character had deleted the C. I guess this
means that on Microsoft operating systems, DEL is treated just like any other
character (although a glyph may not be available).
