MagicFileEncoding 3.0.0

Magic File Encoding

The Magic File Encoding Library is a powerful tool designed to assist you in loading and transforming simple and closed scope character set text files. Whether you're working with txt, xml, json, EDIFACT or similar text formats, this library provides a comprehensive solution to handle various encoding scenarios effortlessly.

.Net Version

• .Net 8: Magic File Encoding 3.0.0 and newer
• .Net 6: Magic File Encoding 2.0.1 and older

Transformation Considerations

When performing encoding transformations, it is important to be mindful of potential issues that may arise if the target encoding is simpler than the source encoding. Certain characters or language-specific symbols in the source encoding may not be accurately represented or fully preserved in the target encoding.

Thorough testing and validation are recommended to ensure the desired outcome during the transformation process.

Fallback Encoding

The Magic File Encoding Library incorporates a fallback encoding system. By default, it uses ISO-8859-1 (Latin-1) as the fallback encoding. This fallback encoding is specifically designed to cater to the encoding requirements within the German cultural space.

However, it provides the flexibility to modify the fallback encoding through an optional method argument, enabling adaptation to different encoding needs like UTF-8 fallbacks.

Usage

Here are some code examples demonstrating the usage of the code library:

File System

Example 1: Getting the acceptable encoding of a file

string filename = "example.txt";
Encoding fallbackEncoding = Encoding.UTF8;

Encoding acceptableEncoding = FileEncoding.GetAcceptableEncoding(filename, fallbackEncoding);
Console.WriteLine("Acceptable encoding: " + acceptableEncoding.EncodingName);

Example 2: Reading all text from a file using automatic encoding detection

string filename = "example.txt";

string text = FileEncoding.ReadAllText(filename);
Console.WriteLine("Text: " + text);

Example 3: Reading all text from a file and transforming it into a target encoding

string filename = "example.txt";
Encoding targetEncoding = Encoding.UTF8;
Encoding fallbackEncoding = Encoding.GetEncoding("ISO-8859-1");

string text = FileEncoding.ReadAllText(filename, targetEncoding, fallbackEncoding);
Console.WriteLine("Text: " + text);

Example 4: Writing text to a file in a specific encoding

string path = "output.txt";
Encoding targetEncoding = Encoding.UTF8;
string text = "Hello, world!";

FileEncoding.WriteAllText(path, targetEncoding, text);
Console.WriteLine("Text written to file.");

Example 5: Providing writer access to a file in a specific encoding

string path = "output.txt";
Encoding targetEncoding = Encoding.UTF8;

FileEncoding.Write(path, targetEncoding, writer =>
{
    writer.WriteLine("Line 1");
    writer.WriteLine("Line 2");
    writer.WriteLine("Line 3");
});

Console.WriteLine("Text written to file.");

Byte Array

Example 6: Getting the acceptable encoding of a byte array

byte[] bytes = File.ReadAllBytes("example.txt");
Encoding fallbackEncoding = Encoding.UTF8;

Encoding acceptableEncoding = FileEncoding.GetAcceptableEncoding(bytes, fallbackEncoding);
Console.WriteLine("Acceptable encoding: " + acceptableEncoding.EncodingName);

Example 7: Reading all text from a byte array using automatic encoding detection

byte[] bytes = File.ReadAllBytes("example.txt");

string text = FileEncoding.ReadAllText(bytes);
Console.WriteLine("Text: " + text);

Example 8: Reading all text from a byte array and transforming it into a target encoding

byte[] bytes = File.ReadAllBytes("example.txt");
Encoding targetEncoding = Encoding.UTF8;
Encoding fallbackEncoding = Encoding.GetEncoding("ISO-8859-1");

string text = FileEncoding.ReadAllText(bytes, targetEncoding, fallbackEncoding);
Console.WriteLine("Text: " + text);
