Single quote characters are always a problem if you want to typeset
computer code.  It is absolutely necessary that /quoteleft and
/quoteright can be distinguished easily.  This is not always the case
because font designers often prefer "typographic quotes" which are
actually commas.

I don't know whether Jacko, the father of lmodern is on this list, so
I added him to the CC.  The lack of cleary distinguishable (also at
low resolution) single quotes is a pity.  Jacko, is it possible to
create such glyphs halfways easily?  I always considered to make Latin
Modern Teletype as a default font for my xterms and for Emacs but I
hesitated because it's currently very difficult to distinguish between
/quoteleft and /quoteright.

Unfortunately there are not many typewriter fonts available at all.
And there is nothing better today than Latin Modern.

There are several variants of "Courier" available.  But see:

URW Courier (red) is compared with IBM Courier donated to X11 (blue).
This looks like a joke but it's real life.

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
