A package replacement for .Net Standard's UTF8 string encoding/decoding implementation.


As of .Net Core 3.0+ a bug was fixed in Microsoft's UTF8 implementation that changes the behavior of UTF8 string encoding and decoding. This package offers the legacy behavior that is still present in .Net Framework today for maximum compatibility when using .Net Core 3.0+.


Install Text.UTF8.Legacy from the Package Manager Console:

PM> Install-Package Text.UTF8.Legacy


UTF8 String decoding

using Text.UTF8.Legacy;

var bytes = // byte representation of a UTF8 string
var utf8String = Text.UTF8.Legacy.Encoding.UTF8.GetString(bytes);

UTF8 String encoding

using Text.UTF8.Legacy;

var string = "A test string";
var bytes = Text.UTF8.Legacy.Encoding.UTF8.GetBytes(string);
