Special characters in the namespace

I am considering using a character with a diacritic label (e.g. ō) in the namespace for a custom structure. This idea came about as a way to distinguish a product, but I want to be sure that it is not a bad idea, and if there is something like that that will come back to bite me later. I have not seen other examples of namespaces that use special characters in my search, and no similar discussions on this topic, which gives me a pause in the continuation of this path.

I initially considered naming the assembly with a diacritic label, but the first showstopper I came across was trying to digitally sign the assembly. I could not get the special character to appear on the command line, so I got a valid input error. Perhaps there is another workaround for this?

I realized that it makes typing the namespace in Visual Studio more complicated. I do not see this as a serious problem, however, as the character nears the end of the word I use, the word will be quite unique, and with IntelliSense this should not be too big a problem.

Consider the following example contained in the assembly of Macron.dll:

namespace Macrōn.Library
{
    public class MyLibrary
    {
        public string MyProperty { get; set; }
    }
}

, Macron.dll, , Macrōn.Library. , , Macrōn, , - , , , - .
