Cannot parse char argument

[TiTiKy441]

.NET 9 with System.CommandLine 2.0.0-rc.2.25502.107 installed via nuget in Visual Studio, win 10 x64

When I try to use a char type option, I always get Cannot parse argument 'b' for option '--char-option' as expected type 'System.Char'.

Test code:

using System.CommandLine;
using System.CommandLine.Parsing;

namespace TestApp
{
    internal class Program
    {
        static void Main(string[] args)
        {
            Option<char> charOption = new Option<char>("--char-option");
            charOption.Description = "Character option";
            charOption.Required = true;
            charOption.DefaultValueFactory = charOptionValue => 'a';

            RootCommand rootCommand = new RootCommand("Test application");
            rootCommand.Add(charOption);
            rootCommand.Parse(args);

            ParseResult parseResults = rootCommand.Parse(args);

            foreach (ParseError error in parseResults.Errors)
            {
                Console.WriteLine(error.Message);
                return;
            }

            Console.WriteLine("Character option is {0}", parseResults.GetValue(charOption));
        }
    }
}

Results:
