VT100 font, It has weird characters Options

[Guest_Tizoc_*]

I'm using Mac OSX (and this also seems to appear in OS9 as well), and when I set my font to good ol' VT100, the weird "invisibles" for spaces and line wraps appear, and it really clutters up the screen. Now I can use other fonts like Monaco or Courier, but VT100 looks better in bold (its the exact same width bold as it is plain). What I'm trying to get at is, why do those invisibles appear? Is there any way to turn them off or another font that is similar to VT100 in respects of its bold property?
