Multi-Encoding Text Processor

Build a text processor that handles bidirectional text in multiple character encodings for a legacy document conversion system.

Requirements

Your solution must implement a function that processes text files containing right-to-left (RTL) content stored in various legacy encodings and prepares them for display.

Core Functionality

Implement a function process_text_file(data, encoding_name) that:

• Accepts raw bytes as the first parameter
• Accepts an encoding name (string) as the second parameter
• Converts the bytes to displayable format while preserving the encoding type
• Returns the processed bytes in the same encoding

The function should handle at least these encodings:

• UTF-8 (utf-8)
• Windows Hebrew (cp1255)
• ISO Hebrew (iso-8859-8)

Test Cases

• Processing UTF-8 encoded Hebrew text "שלום" (shalom) returns reversed bytes in UTF-8 encoding @test
• Processing CP1255 encoded Hebrew text returns reversed bytes in CP1255 encoding @test
• Processing ISO-8859-8 encoded Hebrew text returns reversed bytes in ISO-8859-8 encoding @test
• Processing mixed English and Hebrew text maintains correct directionality for both scripts @test

API

def process_text_file(data: bytes, encoding_name: str) -> bytes:
    """
    Process bidirectional text from bytes in the specified encoding.

    Args:
        data: Raw bytes containing text in the specified encoding
        encoding_name: The character encoding name (e.g., 'utf-8', 'cp1255', 'iso-8859-8')

    Returns:
        Processed bytes in the same encoding, with text reordered for display
    """
    pass
