Hi Greg, Character and string processing in C# uses Unicode encoding - all characters are 16-bit.
The rules for Identifiers can be found in section 2.4.2 of The C# Programming Language, 4th Edition, Hejlsberg, Torgersen, Wiltamuth, Golde. Read it here: http://msdn.microsoft.com/en-us/library/aa664670(v=vs.71).aspx.

I was wondering if the property names could be stored as ASCII or would be more space. So I coded this and found it works. int ΑΒΓΔθ = 123; long y = 891723; var z = ΑΒΓΔθ + y; (If my pasting fails) the first variable is Greek [alpha, beta, gamma, delta, phi]. I'd never thought about this before, and was a little surprised to see it works, but I guess I'm biased by living in a mostly ASCII world. I had a quick look at the C# spec online, but I can't find any specific statement about what characters are acceptable for variable names. I'm guessing it's Unicode letter and number category characters, which is quite few I reckon! Anyway, so I need an NVARCHAR field to store the property names. Greg K
