Comparison is performed on raw bytes.
This works as you would expect for ascii (i.e. english) text but might not be what you want when strings use mixed case (e.g. “abba” is > “Zorro”) or use letters from non-english alphabets.
strings.CompareYou can also compare with strings.Compare but use ==, > and < instead as it has the same semantics.
Sometimes you want “Go” to equal “go”, which is not the case when using ==. You can do that using strings.EqualFold:

The exact rule is: both string are considered UTF-8-encoded strings and characters are compared using Unicode case-folding.
