How do I get the Unicode value of a character in Go?

Finding the Unicode Value of a Character in Go

In JavaScript, the charCodeAt() method returns the numeric Unicode value of a character within a string. To achieve the same functionality in Go, utilize the following steps:

1. Convert the string to a slice of runes: Go uses the rune type, which represents a Unicode code point, to represent characters. To convert a string to a slice of runes, use []rune(string).
2. Access the rune at the specified index: You can access the rune at a particular index using []rune(string)[index].
3. Print as a character: Format your result using fmt.Printf("%c", []) to print it as a character.

Here's an example code snippet:

<code class="go">package main

import "fmt"

func main() {
    str := "s"

    // Convert string to a slice of runes
    runes := []rune(str)

    // Get the Unicode value of the first character
    unicodeValue := runes[0]

    // Print the Unicode value
    fmt.Println(unicodeValue)

    // Print the character
    fmt.Printf("%c", unicodeValue)
}</code>

This code will print the Unicode value (115) and the character 's'.

Additional Note:

If you don't need the character representation, you can directly access the int32 representing the Unicode value of the rune by using string[index]. This is because runes are aliases for int32 in Go.
