#name ⇒ String (readonly)

Value of the symbol literal

Note that it’s a StringValue, not a String. The reason is that you can get UTF-8 incompatible strings from a valid UTF-8 source using escape sequences like ‘“\xFF”`

These “\”, “x”, “F”, “F” chars are valid separately, but together they construct a char with code = 255 that is invalid for UTF-8.

You can use to_string_lossy or to_string methods to get a raw symbol value.

Returns:

  • (String)
