| 109 | to serialize, deserialize, and compare texts at byte level. The type of |

| 110 | length is integer and is serialized using zero-compressed format. <p>In |

| 112 | byte array to a string. <p>Also includes utilities for |

| 114 | byte array contains valid UTF8 code, calculating the length of an encoded |
|---|
| 115 | string. |
