• Operating System: Windows 11
• .NET Runtime: 8.0.4

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.

• What commands did you run to trigger this issue? If you can provide a
  Minimal, Complete, and Verifiable example
  this will help us understand the issue.

from pythonnet import load
load("coreclr")
import clr
clr.AddReference('System')
clr.AddReference('System.Runtime')
clr.AddReference('System.IO')

import System
file_path = r"path\to\zwnbsp_test_data.txt"

result = System.IO.File.ReadAllLines(file_path)
print(str(result[1][0]))

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);

zwnbsp_test_data.txt
