Specifically, the question is one of Chloë vs. Chloe
That little diacritical mark on the e--the one that looks like a German umlaut--is called a diæresis. It comes from the Greek diairesis "division," and it indicates a place where a vowel is spoken when it otherwise might not be. You might have seen it before, as you've probably read something by one or another of the Brontë sisters, and even in America naïve is usually printed with the diæresis. But other uses have disappeared in America--preëminent now gets a hyphen instead, and coöperate is written without any way to show confuzzled children that it's not pronounced like a misspelled version of what a barrel-maker does.
So... we're trying to decide whether to use the diæresis in Chloë or to just leave it as Chloe. Both are generally accepted spellings. What do you think?
