Details

• Describe what you were trying to get done.

I want to read a file that may contain zero width no-break space characters anywhere in the file. If I read a file using C# into Python using Python.NET, these characters get dropped if they are at the start of a line.

Native C# code does not seem to have this problem:

C#String[] lines = File.ReadAllLines(@"path\to\zwnbsp_test_data.txt");int firstChar = char.ConvertToUtf32(lines[1], 0);int secondChar = char.ConvertToUtf32(lines[1], 1);Console.WriteLine(firstChar);Console.WriteLine(secondChar);
