Two reasons:
- to ensure consistency of presentation when a text string with such characters in another font is switched to this monospaced font
- to allow editors, proofreaders, and other professionals who may need / prefer to work in monospaced fonts to do so

Another reason is that you are a completist designing the ultimate monospace typeface.
Make sure it has small caps and swash italics too ;-)

Aha! I will definitely add them then. Thanks very much!

If you don't mind, what mono ( or group of them ) do you think has done the best job/s of compromising between meeting the optical needs of a mono and the cultural imperatives of Greek?

My of the top of the head guess is that you might say Consolas. Did Luc(as) include greek in his other Monos?

To allow for translation of ancient Greek computer coding into C++ :-)

And Nick, Guilty as charged - mostly. I don't pretend to be making the best Mono. My mania is not that far advanced yet. But I am interested in it being very useful and reasonably complete. Plus it's a great excuse to learn about the Greek forms!

Re. Consolas: the current release only supports monotonic Greek, but the family is being extended to cover polytonic Greek.

What is the extened set for?

Most of it is for Greek polytonic. Monotonic and polytonic are two different orthographies for the Greek language, monotonic being the "modern" one.

A monospace to include polytonic? FF Elementa Greek Polytonic comes to my mind.

What a great suggestion. Thanks!

There's also Courier.

What were Greek typewriters like in the mid 20th century?
Prior to typesetting, I assume manuscripts would have been prepared on typewriters in "polytonic" (actually just "normal" then).
Whole lotta backspacing?
