for variable names you can use all latin, greek, script and gothic
letters. Exceptions are the "one letter" functions or constants:
C, D, E, I, K, N, O and $, which are protected.

K isn't protected, but lives in the System` context and is used
internally e.g. as summation variable. It will not be cleared with
Clear["Global`*].
