What are the consequences of assigning a symbol to a string in programming code?

In Go, a rune is a data type representing a Unicode code point (int32). If you try to assign a rune directly to a string, for example:

var s string
s = 'a' // compilation error

it will cause an error because single quotes denote a rune, while double quotes denote a string.

To convert a rune to a string:

s = string('a')

then the rune is converted into a string of length 1.

Implications:

• Incorrect assignment of a rune to a string causes a compilation error.
• Correct conversion creates a string from a single character.

It is important to understand that rune is a numeric type, while string is a sequence of bytes. Converting a rune to a string creates a UTF-8 encoded string of that character.
