package main

import (
  "fmt"
  "strings"
)

func main() {
  fmt.Println(strings.ContainsAny("Hello World",",|"))
  fmt.Println(strings.ContainsAny("Hello,World",|"))
  fmt.Println(strings.ContainsAny("Hello|World",|"))
}

或者,如果要检查是否只有ASCII字符,可以使用strings.IndexFunc：

package main

import (
    "fmt"
    "strings"
)

func main() {
    f := func(r rune) bool {
        return r < 'A' || r > 'z'
    }
    if strings.IndexFunc("HelloWorld",f) != -1 {
        fmt.Println("Found special char")
    }
    if strings.IndexFunc("Hello World",f) != -1 {
        fmt.Println("Found special char")
    }
}
