This is another area where Unicode has given us "a great improvement over the old method of giving satisfaction". Back in the 1990s on OS/2, DOS, and Windows, a missing glyph might be (a) blank, (b) a simple square with no information, or (c) copied from some other font (common with dingbats fonts). With Unicode, the standard is to show a little box *with the hex digits in it*. Granted, those boxes are a LOT more readable for BMP characters than SMP (unless your text is huge, six digits in the space of one character will make them pretty tiny), and a "Unicode" font will generally include all (or at least most) of the BMP, but it's still better than having no information at all.
