Package dev.gmitch215.bytebox.builtin

Class Text

java.lang.Object
dev.gmitch215.bytebox.builtin.Text
public final class Text extends Object
The platform's own encoders, exposed as themselves.

Every charset beyond UTF-8 costs a table in the binary if the class library provides it, and the isolate already has TextDecoder, which handles every encoding the WHATWG registry lists. Base64 and hexadecimal are here for the same reason: the platform has them and a Java implementation would be bytes spent on something already present.

1.0.0
