MonoGame和XNA一样显示中文会报错，如图，所以需要对英文以外的其他字符做特殊处理。

下面提供让MonoGame支持中文显示的办法：

环境：Visual Studio 2015 ， MonoGame版本3.5.1——这是个比较稳定的版本。推荐使用。

步骤：

1.新建【MonoGame Cotent Pipeline Extension Project】命名为：LocalizationPipeline，删除ContentImporter1.cs，ContentProcessor1.cs

2.复制项目两个文件到项目中LocalizedFontDescription.cs，LocalizedFontProcessor.cs

    /// Normally, when you add a .spritefont file to your project, this data is
    /// deserialized into a FontDescription object, which is then built into a
    /// SpriteFontContent by the FontDescriptionProcessor. But to localize the
    /// font, we want to add some additional data, so our custom processor can
    /// know what .resx files it needs to scan. We do this by defining our own
    /// custom font description class, deriving from the built in FontDescription
    /// type, and adding a new property to store the resource filenames.
    /// </summary>
    class LocalizedFontDescription : FontDescription
    {
        /// <summary>
        /// Constructor.
        /// </summary>
        public LocalizedFontDescription()
            : base("Arial", 14, 0)
        {
        }


        /// <summary>
        /// Add a new property to our font description, which will allow us to
        /// include a ResourceFiles element in the .spritefont XML. We use the
        /// ContentSerializer attribute to mark this as optional, so existing

        /// can be imported as well.
        /// </summary>
        [ContentSerializer(Optional = true, CollectionItemName = "Resx")]
        public List<string> ResourceFiles
        {
            get { return resourceFiles; }
        }

        List<string> resourceFiles = new List<string>();
    }
}

        {
            // Scan each .resx file in turn.
            foreach (string resourceFile in input.ResourceFiles)
            {
                string absolutePath = Path.GetFullPath(resourceFile);

                // Make sure the .resx file really does exist.
                if (!File.Exists(absolutePath))
                {
                    throw new InvalidContentException("Can't find " + absolutePath);
                }

                // Load the .resx data.
                XmlDocument xmlDocument = new XmlDocument();

                xmlDocument.Load(absolutePath);

                // Scan each string from the .resx file.
                foreach (XmlNode xmlNode in xmlDocument.SelectNodes("root/data/value"))
                {
                    string resourceString = xmlNode.InnerText;

                    // Scan each character of the string.
                    foreach (char usedCharacter in resourceString)
                    {
                        input.Characters.Add(usedCharacter);
                    }
                }

                // Mark that this font should be rebuilt if the resource file changes.
                context.AddDependency(absolutePath);
            }

            // After adding the necessary characters, we can use the built in
            // FontDescriptionProcessor to do the hard work of building the font for us.
            return context.Convert<FontDescription,
                                   SpriteFontContent>(input, "FontDescriptionProcessor");
        }
    }
}

3.选中LocalizationPipeline项目点击右键选择Properties，.net 框架改成4.5

4.添加System.Xml.dll引用

5.编译生成LocalizationPipeline.dll复制备用，一般在LocalizationPipeline\bin\Debug中

6.新建MonoGame游戏项目，命名为：MonoGameDisplayChinese，以UWP项目为例

7.找到项目Content目录的Content.mgcb，双击打开它，选中Content右键【Add】【New Item】【SpriteFont Description】命名为defaultFont，在Content目录可以就找到defaultFont.spritefont文件。

接着选中Content.mgcb中Content，添加references ，引用LocalizationPipeline.dll

8.使用Visual Studio打开defaultFont.spritefont,修改XnaContent标签中的Asset的Type值为LocalizationPipeline.LocalizedFontDescription，

9.在MonoGameDisplayChinese新建增加strings.resw（UWP项目.resw，其他项目可以是.resx）

Name可以是任意名字，Value中可以存储使用到的任何中文字符

文件ResourceFiles标签到Asset节点中

<?xml version="1.0" encoding="utf-8"?>
<XnaContent xmlns:Graphics="Microsoft.Xna.Framework.Content.Pipeline.Graphics">
  <Asset Type="LocalizationPipeline.LocalizedFontDescription">
    <FontName>Microsoft JhengHei</FontName>
    <Size>14</Size>
    <Spacing>0</Spacing>
    <UseKerning>true</UseKerning>
    <Style>Regular</Style>
    <CharacterRegions>
      <CharacterRegion>
        <Start>&#32;</Start>
        <End>&#126;</End>
      </CharacterRegion>
    </CharacterRegions>
    <ResourceFiles>
      <Resx>..\strings.resw</Resx>
    </ResourceFiles>
  </Asset>
</XnaContent>

注意：Resx的路径是相对Content目录的路径，前面加了..\，如果是UWP项目..\strings.resx改成..\strings.resw

10.回到MonoGameDisplayChinese项目，选中Content.mgcb，右键Open With，选择JSON Editor打开，任何文本编辑器都可以打开！
