Utf8 (JORAM 5.24.0 API)

java.lang.Object
- fr.dyade.aaa.common.encoding.Utf8

```
public final class Utf8
extends Object
```
Low-level, high-performance utility methods related to the UTF-8 character encoding. UTF-8 is defined in section D92 of The Unicode Standard Core Specification, Chapter 3.
The variant of UTF-8 implemented by this class is the restricted definition of UTF-8 introduced in Unicode 3.1. One implication of this is that it rejects "non-shortest form" byte sequences, even though the JDK decoder may accept them.

16.0

- Method Detail
  - encodedLength
```
public static int encodedLength(CharSequence sequence)
```
    Returns the number of bytes in the UTF-8-encoded form of sequence. For a string, this method is equivalent to string.getBytes(UTF_8).length, but is more efficient in both time and space.
    
    Throws:
    
    IllegalArgumentException - if sequence contains ill-formed UTF-16 (unpaired surrogates)
  - encodedLengthGeneral
```
private static int encodedLengthGeneral(CharSequence sequence,
                                        int start)
```
  - unpairedSurrogateMsg
```
private static String unpairedSurrogateMsg(int i)
```
