Utf8Decoder (Apache Tomcat 8.5.89 API Documentation)

Package org.apache.tomcat.util.buf

## Class Utf8Decoder

- java.lang.Object
- - java.nio.charset.CharsetDecoder
  - - org.apache.tomcat.util.buf.Utf8Decoder

-     public class Utf8Decoder
      extends java.nio.charset.CharsetDecoder

  Decodes bytes to UTF-8. Extracted from Apache Harmony and modified to reject code points from U+D800 to U+DFFF as per RFC3629. The standard Java decoder does not reject these. It has also been modified to reject code points greater than U+10FFFF which the standard Java decoder rejects but the harmony one does not.
