Golang 从符文转换为字符串

Scanner.Scan()runeScanner.Scan()Scanner.Moderunetext/scanner

runeScanner.Next()

c := b.Next()
fmt.Println(c, string(c), strconv.QuoteRune(c))

输出:

97 a 'a'

runestringruneint32string

将有符号或无符号整数值转换为字符串类型会生成一个包含整数的UTF-8表示形式的字符串.

因此:

r := rune('a')
fmt.Println(r, string(r))

输出:

97 a

stringfor ... range

for i, r := range "abc" {
    fmt.Printf("%d - %c (%v)\n", i, r, r)
}

输出:

0 - a (97)
1 - b (98)
2 - c (99)

string[]rune

fmt.Println([]rune("abc")) // 输出: [97 98 99]

试试看Go Playground号公路上的例子.

Note:

Scanner.Scan()

c := b.Scan()
if c == scanner.Ident {
    fmt.Println("Identifier:", b.TokenText())
}

// 输出: "Identifier: a"
