Redirects console output (Console.WriteLine) to Unity (Debug.Log). Keep in mind that this will probably add some internal logging of Unity to your Editor console.

UnityConsoleRedirect.cs

using System;
using System.IO;
using System.Text;
using UnityEngine;

namespace Generator.Scripts.Runtime.Utilities.Logging
{
    /// <summary>
    /// Redirects console output (Console.WriteLine) to Unity (Debug.Log)
    /// </summary>
    public class UnityConsoleRedirect : MonoBehaviour
    {
        public void Start()
        {
            Console.SetOut(new UnityTextWriter(false));
            Console.SetError(new UnityTextWriter(true));
        }

        private class UnityTextWriter : TextWriter
        {
            private readonly StringBuilder _buffer = new();

            private readonly bool _isError;

            public UnityTextWriter(bool isError)
            {
                _isError = isError;
            }

            public override void Flush()
            {
                if (_buffer.Length <= 0) return;

                if (_isError)
                    Debug.LogError(_buffer.ToString());
                else
                    Debug.Log(_buffer.ToString());

                _buffer.Length = 0;
            }

            public override void Write(string value)
            {
                if (string.IsNullOrEmpty(value))
                    return;

                _buffer.Append(value);

                var len = value.Length;

                if (len <= 0) return;

                var lastChar = value[len - 1];

                if (lastChar == '\n')
                    Flush();
            }

            public override void Write(char value)
            {
                _buffer.Append(value);
                if (value == '\n')
                    Flush();
            }

            public override void Write(char[] value, int index, int count)
            {
                Write(new string(value, index, count));
            }

            public override Encoding Encoding => Encoding.Default;
        }
    }
}

Suggestion of Rich Wepner : I guess you probably want to do the same thing with Console.SetErr as well? 💡
