// Now that we've learned about arrays, we can talk about strings.

// For now, just focus on the fact that strings are arrays of

    // print() function (which uses std.fmt.format() function) to
    // print out a UTF-8 character. Otherwise we'd see '100', which
    // is the decimal number corresponding with the 'd' character
    // in UTF-8.
    // While we're on this subject, 'c' (ASCII encoded character)
    // would work in place for 'u' because the first 128 characters
    // of UTF-8 are the same as ASCII!
