How deeply does Go in Practice, Second Edition cover UTF-8?

Places UTF-8 in Go's data-encoding workflow but stops short of byte-level mechanics or conversion code.

UTF-8

As explained in Go in Practice, Second Edition

UTF-8 is a variable-width Unicode character encoding that represents Unicode text as sequences of bytes.

UTF-8 is a variable-width Unicode character encoding that represents Unicode text as byte sequences. Go handles data internally as UTF-8, but systems may exchange Base64, JSON, XML, or other encodings, requiring translation at system boundaries. section 1.2.2

Practical implications for Go data handling:

Treat UTF-8 as Go's native text representation. section 1.2.2
Use standard-library packages and interfaces to convert encoded data into local objects or structs. section 1.2.2
Add external encoding packages when the required translation is not provided directly. section 1.2.2
