This is a nice fix for the console gibberish issue, I'll try to including it on the Core DebugPlugin, as an optional configuration parameter.

Hi, @usagirei
Is there any chance to use GetACP() to determine system Code Page ?

using System;
using System.Runtime.InteropServices;

class Program {
    [DllImport("kernel32.dll")]
    private static extern uint GetACP();

    static void Main(string[] args) {
        // The following line will show "GetACP() = 932" for Japanese Windows system.
        Console.WriteLine("GetACP() = {0}", GetACP());
    }
}

And you could use GetACP() in the DebugPlugin something like this :

namespace UnityInjector.Plugins
{
    ...
    public class DebugPlugin : PluginBase
    {
        [DllImport("kernel32.dll")]
        private static extern uint GetACP();

        ...
        public void Awake()
        {
            if (this.CodePage != -1)
            {
                if(this.CodePage == 0)
                {
                    this.CodePage = GetACP();
                }
                Console.OutputEncoding = ConsoleEncoding.GetEncoding(this.CodePage);
                ...
            }
        }
    }
}

UnityInjector 1.0.3.0の対応時に、ConsoleCodePage相当のコードがUnityInjector側に取り込まれたので、自動コンパイル対象から外しました。
つけたり外したりせわしなくて申し訳ない！

@neguse11
Interesting, i'll have a look at GetACP, -1 = disable (since it breaks text mirroring in some cases), 0 to Automatic via GetACP, and >1 manual

EDIT: Included, thanks for the tip, check in UnityInjector 1.0.3.4, 0 should call GetACP
