[I] Difference between logs which stores in files and logs in UI [airflow]

[via GitHub]

Zoynels opened a new issue, #39686:
URL: https://github.com/apache/airflow/issues/39686

   ### Apache Airflow version
   
   2.9.1
   
   ### If "Other Airflow 2 version" selected, which one?
   
   _No response_
   
   ### What happened?
   
   We print to log some information and saw that logs has difference between 
logs which stores in files and logs in UI (also downloaded logs). Difference is 
in "empty lines" (we need them in some cases).

   ### What you think should happen instead?
   
   I think that they should be equal in information that was loggen and saved.
   
   ### How to reproduce
   
   ```python
   from airflow import DAG
   from airflow.decorators import task
   import pendulum
   
   with DAG(
       dag_id="test_logs",
       catchup=False,
       start_date=pendulum.datetime(2024, 5, 17, tz="UTC"),
       schedule=None,
       tags=["logs"],
   ) as dag1:
   
       @task()
       def print_log1():
           print("1\n2\n\n3\r\n4\n\r5\n \n6")
           import logging        
           logger = logging.getLogger(__name__)
           logger.info("1\n2\n\n3\r\n4\n\r5\n \n6")
       print_log1()
   ```
