 ## Utilities
 
 ### util.utf8encode
+Encodes a string into a UTF-8 bytes array
+```javascript
+let bytes = envoy.util.utf8encode("test") // Uint8Array(4) [116, 101, 115, 116]
+```
+**Parameters:**
+- string (required): string (`"test"`) - the string to encode
+
+**Returns:** Uint8Array (`Uint8Array(4) [116, 101, 115, 116]`) - the UTF-8 encoded bytes
 
 ### util.utf8decode
+Decodes a UTF-8 bytes array into a string
+```javascript
+let string = envoy.util.utf8decode(new Uint8Array([116, 101, 115, 116])) // "test"
+```
+**Parameters:**
+- bytes (required): Uint8Array (`Uint8Array(4) [116, 101, 115, 116]`) - the bytes to decode
+
+**Returns:** string (`"test"`) - the UTF-8 decoded string
 
 ### util.stringToBytes
+Encodes a string into a bytes array
+```javascript
+let bytes = envoy.util.stringToBytes("test") // Uint8Array(4) [116, 101, 115, 116]
+```
+**Parameters:**
+- string (required): string (`"test"`) - the string to encode
+
+**Returns:** Uint8Array (`Uint8Array(4) [116, 101, 115, 116]`) - the encoded bytes
+
+**Warning: While this method is similar to [util.utf8encode](#util-utf8encode), it does not handle UTF-8 encoding for characters outside of the 8 byte range, causing unexpected outputs for UTF-8 characters.**
 
 ### util.bytesToString
+Decodes a bytes array into a string
+```javascript
+let string = envoy.util.utf8decode(new Uint8Array([116, 101, 115, 116])) // "test"
+```
+**Parameters:**
+- bytes (required): Uint8Array (`Uint8Array(4) [116, 101, 115, 116]`) - the bytes to decode
+
+**Returns:** string (`"test"`) - the decoded string
