Golang : Convert a rune to unicode style string \u
Continuing from previous tutorial on how to get escape characters or \u unicode style string. These are some additional methods to convert rune to unicode style string.
package main
import (
"fmt"
)
func main() {
// use %x for single rune
fmt.Printf("\\u%x\n", 'お')
// fmt.Printf("\\u%x\n", 'おはよう') -- will not work
// use %+q for multiple runes
fmt.Printf("%+q\n", "おはよう")
}
output :
\u304a
"\u304a\u306f\u3088\u3046"
Another way :
package main
import (
"fmt"
)
func main() {
u := fmt.Sprintf("%U", 'お')
fmt.Println(u)
}
Output :
U+304A
or use strconv.QuoteRuneToASCII()
function.
package main
import (
"fmt"
"strconv"
)
func main() {
// translate character to rune
r := rune('お')
// extra the unicode \uxxxx value
unicode := strconv.QuoteRuneToASCII(r)
fmt.Println(string(r)+" unicode string value is : ", unicode)
}
Output :
お unicode string value is : '\u304a'
