  13. STRINGS • Go source code is always UTF-8. • A string holds arbitrary bytes. • A string literal, absent byte-level escapes, always holds valid UTF-8 sequences. • Those sequences represent Unicode code points, called runes. • No guarantee is made in Go that characters in strings are normalized. • https://blog.golang.org/strings Berlin Expert Days 2015 | Dennis Kluge | Slide 13
