for-range over a string to get the runes (Unicode code points) in the string.
for i, rune := range aString {
... // use the rune
}
i is the start index of the bytes of the rune. The size (count of bytes) of each rune can be got but the process is not very smooth. The following way is more smooth to rune sizes:
import "unicode/utf8"
var str = aString
for {
rune, size := utf8.DecodeRuneInString(str)
if size == 0 {
break
}
str = str[size:]
... // use rune
}
