C# Mono - 支持编码答案

【问题标题】：C# Mono - Encoding supportedC# Mono - 支持编码
【发布时间】：2015-10-31 20:21:14
【问题描述】：

我正在尝试在控制台中编写一个小程序，在 Windows 中效果很好，但是当我在 Ubuntu over Mono 项目中运行它时，即使我在良好的编码（iso -8859-1, UTF8, Unicode)

TextWriter tw = new StreamWriter(File.Open(@"C:\Temp\data.txt", FileMode.CreateNew), Encoding.GetEncoding("iso-8859-1"));
tw.WriteLine("éèçàôûêâ");
tw.Close();

那么 Mono for C# 支持什么编码？
