Not using iconv. I also remember this initial character set of graphics
cards, with its small triangle at code 0x7f. It is not supported by
iconv, because
  - Most software nowadays has a character output layer that handles
    control characters. Hardly any software uses the x86 16-bit 'INT'
    calls that produces these fancy glyphs.
  - Even when you have software that produces these fancy glyphs for
    screen output, as soon as you redirect output to a file and view
    the file with another program, the glyphs won't appear.
