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

a: '\x03abc'

{
    a: "A2FiYw=="
}
