[bug-gnu-libiconv] Converting control characters to printable symbols

[Adam Nielsen]

Hi all,

I'm working on a binary file viewer, and one thing that bugs me with
pretty much all non-DOS viewers is that none of them can display
control characters (ASCII codes < 32.)

I've found that iconv is great for converting the old US DOS character
set (CP437) to UTF8, but it leaves all the control characters
untouched.  (Which is fair enough, things like newlines and tabs are
probably supposed to stay the same.)

I vaguely recall the glyphs the standard PC video BIOS uses for
control characters being available elsewhere in the Unicode character
set, so if I'm remembering correctly is there any way to map these
control characters to the appropriate glyphs using iconv?

Thanks,
Adam.
