Yes, and that's the character that was immediately overloaded to used to mean a whole bunch of other things, because ASCII only included 95 printable characters, and did not include a prime symbol, an 'okina, or a left single quotation mark.

For that reason, U+0027 is not an apostrophe anymore. As the only ASCII character that can be used for a long list of uses, it's been massively overloaded, which is why Unicode currently defines U+0027 as a typewriter apostrophe and U+2019 as a real apostrophe.
