Maybe try Monospace, 'BPG Courier GPL' or 'BPG Courier S GPL'.
I'm finding the line spacing with Monospace more useful though, and it
seems better balanced and better readable than 'Source Code Pro'.

For proportional fonts Helvetica is awesome (the licence for it was
well worth it to me).

Monospace and Helvetica also go together very well.

I bet this has come up before.  I'll tell you what I did to solve
this.

For the most part, I use Debian on servers and I access them through a
windows desktop, so for me, the solution starts on Windows.  There's
different keyboards you can configure on windows but none of them get
you at arbitrary unicode characters.  What I did do was use a program
named kbdedit which allowed me to craft a key mapping for my keyboard
so I could create the various keys I wanted to use, and for the
characters that I don't use regularrly, I just copypaste the code from
either a web page or from kbdedit into the window, be that putty or ms
word.

What I did was create a heavily compose-key key mapping.  I use the
right hand alt key as the compose key.  So for me ½ is simply alt-1
2.  The accented letters like é is just alt-e '.

Is there a way to create a similar keyboard mapping in X-windows on
debian based systems?

I've often wondered what a "full unicode keyboard" might look like.
Unfortunately composing only gets you so far.  There's definitely some
common characters you can do by composing 2 characters logically but
it's far far from complete.  I do wonder if someday we'll see larger
physical keyboards with some extra keys at the top to eventually
access all characters via some logical interface rather than having to
know their unicode code point.

Easy. I configured my CAPSLOCK key (which is useless IMO) to be
my X compose key. So entering COMPOSE-4-5 does ⅘, and COMPOSE-<-3
does ♥. You can even define your own compose seqs, like I did with
♀ (COMPOSE-o-+) and others.

The nice part is that it works for /all/ X11 applications, even
in a plain old xterm (I'm writing this mail in vim in an xterm).

Might be time for a new font. I like Inconsolata, but l1I!
should never look similar, nor O0@ or S$.

I've been pretty happy with the Intel One Mono font lately, it seems to 
incorporate the lessons learned from previous attempts at a highly 
readable mono font and I find it extremely legible. There are complaints 
about certain features being "ugly", but I'm well into a stage of life 
where I care more about being able to easily read the text without 
eyestrain than what it looks like on a sample sheet.

  My eyesight sucks like a black hole with daddy issues, so I like fonts
  that are a bit larger than most.  My favorites on xterm:

  * xft:Menlo-Regular:pixelsize=20:bold
  * xft:Bitstream Vera Sans Mono:pixelsize=21:bold
  * xft:Cascadia:pixelsize=22:bold
  * xft:FiraMono-Regular:pixelsize=22

  Your examples above are very readable with Menlo.  These aren't bad:

  * xft:Edlo:pixelsize=21:bold
  * xft:Inconsolata-Bold:pixelsize=25:bold
  * xft:Meslo LG S:pixelsize=20:bold
  * xft:Meslo LG S:pixelsize=21:bold
  * xft:UbuntuMono-B:pixelsize=25:bold

  I run two xterms side-by-side on a 23-inch monitor:

/usr/local/bin/xterm -geometry 80x40-0+0 -j -b 10 -sb \
  -si -sk -ls -u8 -sl 4000 -cr blue -bd black -bg white \
  -fa xft:Menlo-Regular:pixelsize=20:bold -title Remote

  For browsing (Firefox), my "prefs.js" file holds:

user_pref("browser.display.use_document_fonts", 0);
user_pref("font.default.x-western", "sans-serif");
user_pref("font.internaluseonly.changed", false);
user_pref("font.minimum-size.x-western", 18);
user_pref("font.name.monospace.x-western", "DejaVu Sans");
user_pref("font.name.sans-serif.x-western", "sans-serif");
user_pref("font.name.serif.x-western", "DejaVu Serif");
user_pref("font.size.fixed.x-western", 18);
user_pref("font.size.variable.x-western", 18);

I'll give a shout-out for Hack,¹ which I can't fault for use in
xterms. Comparingxterm -geometry 80x25+0+0 -fa hack -fs 16
with   xterm -geometry 80x25+0+0 -fa inconsolata -fs 18
(to make the sizes roughly the same), I find the inconsolata
stroke width on the basic Roman alphabet is a little spindly.

fractions is ugly, too: ½ ⅓ ⅔ ¼ ¾ ⅛ ⅜ ⅝ ⅞. The ‘’ quotes
are pretty, though.

Of course, these criticisms only apply to the implementation from
fonts-inconsolata, rendered on xterms, as compared with fonts-hack.
I don't know whether they arise because the font is a work in
progress, and the implementation hasn't yet caught up: eg, the
capitals with diacriticals look fine in the sample off the web at:

Indeed.  Also, ({[ and )}] are character groups that must be visibly
different, or else any terminal or programming work you do is going to
be a massive pain.

You appear to be asking about the shell prompt.

In bash, the shell prompt is defined in the PS1 variable, which stands
for "Prompt String One (1)".  The last character is the numeral 1, not
the capital letter I.
