Um, no, for English:
Right quote is ’ U+2019, it's used also for apostrophe in English.
Left quote is ‘ U+2019
Web pages sometimes use HTML entities, but UTF8 epub can use them directly.
There is usually end of paragraph or a space after ’ (right quote) unless it’s an apostrophe as in ’90s or won’t.

Unicode Hex Character Code ’ is "Private use two" and should not be used as ’. It should be replaced with Right quote ’ U+2019, which in English doubles as the apostrophe.
Unicode Hex Character Code ’ is ' and is the typewriter apostrophe or programming single quote. It should only be in ebooks in code examples or simulation of typewriters, consoles, DOS, teleprinters and telex messages.
Same applies to ", it's the programming double quote and it also should only be in ebooks in code examples or simulation of typewriters, consoles, DOS, teleprinters and telex messages.
the `should never be in English as left quote it's for à è etc.
2' 7" or 2’ 7” are wrong, the prime and double prime should be used 2′ 7″ for feet & Inches or minutes & seconds (time or angular degrees)
Also make clear if you mean Unicode or ASCII, but obviously you mean Unicode.
The Microsoft Windows code page CP1252 (sometimes incorrectly called ANSI or ISO-Latin) contains the typographic apostrophe at 0x92, which is why the ’ might be displayed for Unicode Hex Character Code ’. But Unicode uses U+2019 for apostrophes (also the English closing or right quote)
