ord('a') = 97

They are supported as simple conversions:

ch := rune(97)
n := int('a')
fmt.Printf("char: %c\n", ch)
fmt.Printf("code: %d\n", n)

Output (try it on the Go Playground):

char: a
code: 97

Note: you can also convert an integer numeric value to a string which basically interprets the integer value as the UTF-8 encoded value:

s := string(97)
fmt.Printf("text: %s\n", s) // Output: text: a

Converting a signed or unsigned integer value to a string type yields a string containing the UTF-8 representation of the integer. Values outside the range of valid Unicode code points are converted to "\uFFFD".

It appears that a simple uint8('a') will produce a correct output. To convert from integer to string string(98) will suffice:

uint8('g') // 103
string(112) // p
