Valid that is if it's enclosed in a class and a namespace :facepalm:

That's nothing. In Haskell, you can use punctuation *as well*!
More precisely, you can use names consisting only of punctuation, which
then become infix operators. Or you can use names beginning with a
letter and then continuing with any character except for a rather small
set of standard ASCII characters considered to be "punctuation" as per
the Haskell Language Report [*not* as per Unicode].
Some folks like to do things like define a function composition operator
who's name is the *actual* Unicode code-point for the function
composition operator. (These same people tend to use "λ" in place of "\"
too, which is allowed by the syntax rules...)
Amusingly, you cannot define a Γ function in Haskell, because Γ is an
uppercase letter. You can, however, define a γ function if you like...

IIRC uppercase because you can chisel them in stone. lower case after
starting writing regularly on things like papyrus that allows curves
more easily.

It has to be. Missing is e.g. the one I introduced*. Symbol is a upside
down hat with two ears sticking out. Pronounced "Wabbit" and can be used
at the end of an equation to signify that the reader is not supposed to
understand why this equation is used until later.
The need for this symbol arises from the fact that mathematical
derivations are often presented not the way the idea came up but in the
reverse order. Mainly because that appears to be the style of
mathematics: never admit that you had a brilliant idea to start with.
This practice is meant to impress the readers, but mainly results in too
many kids deciding that they will never understand mathematics.
*) I did that in the proceedings of a very small conference, so I don't
blame anyone not to have read it.

Yup pretty much created by transcripters to speed up copying. Some of the
letters you can see how this developed Xi and Epsilon for example; Nu and
Omega on the other hand...

There's no reason this should piss off your coworkers any more than
overloaded operators do. It's all essentially the same problem.
C# is just a unicode-aware programming language. You can't use any non-di
git
non-punctuation character. You can use unicode letters. Just because they
don't look like letters in *your* alphabet doesn't mean they aren't lette
rs.
That said, you probably ought have a really good reason to use non-ASCII
characters just like you ought have a good reason to overload operators.
Like, say, naming a function "Γ".
