The VT100 has 32 special graphical characters. The usual vt100 extended
xterm fonts have these at 0x00..0x1f.
QT's iso mapping leaves 0x00..0x7f without any changes. But the graphicals
come in here as proper unicode characters.
We treat non-iso10646 fonts as VT100 extended and do the required mapping
from unicode to 0x00..0x1f. The remaining translation is then left to the
QCodec.
