You suggest to replace different types of whitespace symbols with 0x20.

Have I understood you correctly?

 The console fonts run in a tty.  I think the appropriate
description might be "what you ask for is what you get".

 If you are looking at html in a browser, the browser makes decisions
about how to process the nbsp entity.  But for plain text, you get
what the current font produces for that character.  The font doesn't
add a linefeed of its own accord - long lines just appear to wrap onto
the next line of the screen.

 As a side-note to the request, you can change your local psfu fonts
using psftools (from freshmeat if your distro doesn't supply it):
txt2psf to reproduce the font in a text form ('-' for blank pixels,
'#' for lit pixels),

 edit it to add more characters to the space glyph - e.g.

Unicode: [00000020];[000000a0];[0000202f];

 (to add U+202f to an existing U+00a0).

 and then txt2psf to convert the altered file to a psfu font.

 I was interested to see your request, and _surprised_ that you have
this character mapped on your keyboard.  I thought people would just
type a regular space - shows how little I know.

I added your patch and new fonts, but I need more testing it. Thanks!
