+# Bytes
+
+CUE distinguishes between a `string` and a `bytes` type.
+Bytes are converted to base64 when emitting JSON.
+Byte literals are defined with single quotes.
+The following additional escape sequences are allowed in byte literals:
+
+    \xnn    // arbitrary byte value defined as a 2-digit hexadecimal number
+    \0nnn   // arbitrary byte value defined as a 3-digit octal number
+
+
+<!-- CUE editor -->
+```
+a: '\x03abc'
+```
+
+<!-- JSON result -->
+```json
+{
+    a: "A2FiYw=="
+}
+```
