In lexicographic ordering, to guarantee an upper bound that includes every string starting with a given letter, extend that letter with the largest possible characters. Using Zs after the letter makes the bound larger than any possible extension of that letter because Z is the last character in the alphabet, so no string starting with the specified letter can exceed a string like the letter followed by Zs. For example, bound with A and many Zs will be greater than any name starting with A, no matter what comes after. Other options don’t reliably cover all extensions: a dash or a closing bracket isn’t guaranteed to come after all possible trailing characters, and using Ys wouldn’t surpass strings that extend with Zs. Hence, appending Zs after the last letter provides a safe, comprehensive upper bound.
